They pack your take out with all the essentials (bib, table cover, gloves, lemon and salt). Ate in the restaurant before too and never had any issues. Highly recommend if you want a solid Cajun place to dine in or dine at home. Location: next to Albertsons. Plenty of parking. read more

We had the Combo 2 which was more than enough for two people. The peeled shrimp, crawfish, and snow crab were fairly delicious and juicy. We came when they have the live crawfish as opposed to frozen, and it probably made a world of difference. The spicy Torpedo sauce was also pretty good blend of flavors, a little spicy, tangy, and sweet. Service is very professional and attentive. Even had a cool smokey bubbly hand wash cup. Definitely will be back if we are craving some seafood boil. read more

10/10, not the typical sauce though it was a little sweet, not sure what that was but it was still amazing nonetheless!!! All of the girls working 4/10 were amazing! They were sweet, professional, and quick. Jane and Kennis so sweet, so kind, loved them. It's nice in here, they play like a lofi mix of the new hits. would come again i also wanted to add this super cool thing they do at the end !!!! i've never been so entertained. read more

2/14/2026 Valentines Day This review is live as I am still at the location. Yelp said it's closing in 51 mins I would give it a negative star if I could. Long wait list, many tables open since 30 mins before I wrote this review, but no one cleaned the tables so they could call ppl in. They let new people came in and wrote their names down on the wait list without telling them that they can't take walk ins anymore. Some people were smart enough to cross their names out and left. It's looks like they're understaffed BUT they were still taking to-go orders. WTH! VERY BAD SERVICE! read more

The Submarine Crab - Cajun/Creole Near Me - Diamond Bar, California

Trying this restaurant for the first time. Came here for lunch with my family. Restaurant was nice and clean, both inside and outside. I love their submarine theme decors. The staffs here are friendly and attentive. Being here for the first time, they were able to explain how things work. The food here is similar to Boiling Crab and Kickin Crab. You order your seafoods by the pound, then select your sauce. They have set combos you can order from, which makes ordering very easy. We got the Combo #1. We selected Shrimp, Clams, and Mussel. We opt for the Torpedo sauce, which is a combination of Garlic Butter, Classic Cajun, and Lemon Pepper. We also added the Fish and Chips. We didn't wait long before our foods came out. Foods were delicious. The Torpedo sauce goes well with the Seafoods. We enjoyed every bites. The Fish and Chips were also very good. We love it here. Would definitely come back again in the future to try their other items. read more

I was eager to try this place and it was easy to make a reservation as well. The service was quick and attentive and the place is very clean. As for the food, I give 3 stars since it is definitely fresh seafood, however the taste was way too salty for me. I tasted more saltiness than the garlic butter and their Cajun sauce. The garlic noodle is pretty decent. The portion is less than moderate when it says on Combo B that includes 4 sausages, literally it's 4 small pieces of sausage. Thank you for the service though! read more

We love coming here as opposed to other seafood boil places because you don't have to wait ridiculously long to be seated. You are welcomed and served right away. Staff is friendly.

Food is 10/10 good flavor all around. We are definitely turning into regulars here. read more

The Submarine Crab - Cajun/Creole Near Me - Diamond Bar, California

It's not as fresh as other seafood locations. Maybe it was just and off day. Prices are too high for the quality. But the staff was kind.

I can't believe this place opened AFTER I moved out of my parents' house in diamond bar! I always be craving seafood broil. We saw a reel on IG and decided to try it out since it was right next to my mom's. We went on a rainy Friday night and it wasn't too busy! I like that they play sports on the TV! The servers were super kind and food with delicious. The price is not bad either. We spent approximately $185 for 6 people. Shrimp is always my favorite and the cajun fries! Will definitely come back here to get my seafood broil fix. read more

This place isn't bad. There are other places I prefer as the sauce at those other places are better. However they do give you plenty of sauce on the side. They also have liquor here which is a plus. I would say I was pleasantly surprised with the service. It was great. Unfortunately we came at the wrong time. Apparently crawfish was not in season and was frozen. We missed live crawfish by a day. The clam was a little mushy and not that great. But the shrimp and Cajun fried rice was good. I originally was going to give this place 3 stars but service was on point and they served Tito's with soda where most similar places have beer. And the hand wash was plus! The place was clean and kept up very well. read more

Absolutely delicious Portions are great Flavors are on the spot Must try if crab boil is your thing read more

Here's a polished version of your review while keeping your tone and enthusiasm: Way better than Boiling Crab, in my opinion. The Torpedo sauce is my favorite--super flavorful, and the seafood is incredibly fresh. So many spots don't even use live seafood, but this place does it right. The butter garlic clams are something I literally dream about, and I always take extra Torpedo sauce home to pour over rice. Game changer. I also have to get the fish and chips--tasty catfish with Cajun fries. So good. Sunny was my server and she was so sweet and attentive. Service is always on point. They regularly have sales and a solid happy hour. This place is definitely my go-to! read more

The Submarine Crab - Cajun/Creole Near Me - Diamond Bar, California

Service was great. Food was generally okay, but the dishes weren't covered in sauce, so they cooled down faster than at similar places. I wouldn't recommend the lobster tail--it seemed either overcooked or not fresh. Also, the 4 sausage is just 4 small pieces, which wasn't what my friend and I expected (and I now see others have mentioned the same). I later found out the restaurant had a temporary closure in October 2025 due to a health code violation, which I didn't know before visiting. Taking everything into account, I don't think I'll come back... read more

The Submarine Crab - Combo 2 (2 corns, 2 potatoes, 4 sausages included) - Cajun/Creole Near Me - Diamond Bar, California

Great delicious seafood with friendly, helpful service. We hada late dinner after work. Even though there were only two tables in the restaurant, the friendly server did not rush us. She was really helpful with the order and attentive. The seafood pasta was super yummy and flavorful; it matched the fries. We also shared a combo meal, and that was like a feast for 5!!! All the fresh seafood marries well with the house sauce. We were surprised and amazed! It matched the fries. We also shared a combo meal, and that was like a feast for 5!!!

This place is AMAZING. The Combo deals are always so worth it! It just depends on what you want inside for what the combo deals are offering. The flavor (torpedo) is SO GOOD. I definitely recommend that! As well as the Cajun fries. (If you're a crawfish lover PLS COME HERE WHEN ITS CRAWFISH SEASON!! ITS WORTH IT!!) They also have mouthwash and this cute way to wash your hands after your meal that has bubbles flowing out from a glass container! Super cute! Staff is super nice and friendly. They're very attentive and caring. Cleanliness and ambiance of the place is perfect. Super clean and relaxing while just chowing down your seafood boil. 10/10 This place ALWAYS a go to for me! read more

I decided to come back. I think its better to come in between lunch and dinner hour. Not too many people, less crowded. Service was good! Server explained everything pretty well on the menu. It was comfortable sitting inside. The seafood was fresh. And the clam chowder was hot and delicious. Garlic bread taste good with the clam chowder. read more

YES & YES!! The food & service is amazing. The place was so clean & inviting. We had combo 2 with shrimp & lobster we ordered fries & garlic bread They have specialty drinks that have lots of character. We loved it & will be back read more

Called ahead for a takeout order. Staff were friendly and got our order easily, and didn't want too long for our order to come either. Inside is clean and plenty of space. Got their combo 1 with head on shrimp. Overall the flavor is pretty solid. I feel like the shrimp were overcooked slightly. Pricing is slightly on the high side but I still feel like it's a good local spot for a seafood boil. I'd come back to try again but would have higher hopes next time. read more

I am obsessed with this place. The servers are starting to recognize me. Clean and simple with a submarine theme. I can't get enough of their food! The seafood is really fresh. Head on shrimp is PLUMP (The clams are almost always live) and the SAUCE. I could bathe in it. If you like the garlic noodles and Cajun fries are amazing too. If it's just you- you can get a lb of shrimp and some white rice for under $25! That's a steal for Cajun boil. read more

Best place to get seafood boil now! Ordered to go, ready in 15-20minutes. Service was quick and nice! Inside was very clean. We ordered the combo 3, it was enough to feed us 4 with leftovers. For the sauce we got the house one, super good! They have a lot of sauce too, not like other places which always skimped on the sauce. Overall, it's a great place to try! P.S. sorry for the bad picture, we all ate it right away because it smells so goood!!! read more

The Submarine Crab - Cajun/Creole Near Me - Diamond Bar, California

I'm so glad I found this location of Submarine Crab! I have held off from eating local shrimp boil because nothing compared to the location in Garden Grove. I'm glad they expanded and opened this location in Diamond Bar! My fiancé booked a Valentine's Day dinner reservation for us at 7:30pm. We arrived 10 minutes early and we're greeted and seated right away. The restaurant is quaint and straight to the point - no frills, clean and simple theme decorations. The restaurant seats about 15 tables. Once seated, we reviewed the menu and ordered just enough food so that we were full and no left overs - sweet potato fries, combo 2, and drinks. There is a free beverage when you follow them on IG or make a post and it is so good! I can't remember the name of the drink...Captain something. Very refreshing and cool drink with dry ice for visuals. The sweet potatoe fries were a good palate cleanse from all the garlic, although I definitely want to try the garlic noodles next visit. Once we had our food it was time to get serious with a bib, no gloves because peeling shrimp heads requires some finger grip. The torpedo sauce is a mix of all the seasonings (like the whole shabang but better, if you can imagine that). The shrimp was big, juicy, and delicious; so were the lobster tails. The drinks were very creative and had well thought-out ingredients and presentation. Definitely a nice touch. For Valentine's Day, we were given a complimentary bottle of wine which was such a nice gesture. We left here satiated, happy, and filled with love. Overall, a great option and price point for Cajun Seafood Boil. The quality and flavor are so worth it! read more

Food is mid here, but they try to make up for it with a cool experience and good pricing/deals. If you are not too particular about your Cajun food and want to try something new, come here. Otherwise, take a pass. The servers are fast and really nice and they have this cool soap bath after you finish to wash your hands. Chill vibes to come with friends. read more

The Submarine Crab - Mussels crayfish and shrimp - Cajun/Creole Near Me - Diamond Bar, California

Been here twice and enjoyed myself thoroughly both times. What keeps me coming back is their torpedo sauce. It's a unique flavor compared to other seafood boils in that it trends more on the sweeter side, which makes sense since this restaurant serves everything with a Vietnamese twist. This also shows up in their variety of side dishes and entrees, so if you come with someone who may not be a big fan of seafood, they have options. I also enjoy they have a selection of cocktails and generous happy hour deals. First time I came I shared a Combo 3 and the four of us were able to almost finish the entire pot. This time I got a pound of shrimp and a pound of their snow crab legs and I couldn't finish! Very big portions. Shrimp was not overcooked, easy to peel, and bouncy. The crab legs didn't taste frozen and were very succulent. They give you scissors and a cracker. I also added potatoes, but avoided the sausages as one sausage is actually just a slice so if you're ordering two sausages you're only getting two small slices. Each table comes with gloves and bibs. We also tried their coconut snails, scallops, garlic noodles, shaken beef, and fries. Nothing disappointed. This place seems family run. They used to have a server who did magic tricks but I think he moved so if you see older reviews mentioning magic, that's why lol Plenty of parking in this plaza. Did not have to wait long to get a table either time, but did make a reservation because I had a big party the last time. My only suggestions for improvement is to make the sausage portions a little more worth their a la carte price and maybe make the playlist bigger because we heard it repeat a few times. Would come back again! read more

I finally got the opportunity to try the Cajun-style seafood boil at Submarine and it did not disappoint. My original plan was to try both the shrimp and crawfish, but I got talked into just giving the crawfish a chance. They were plump, spicy and tangy, and were consistently juicy. I'm used to smaller crawfish that are doled out to you in large quantities. There were maybe 8-9 crawfish in the bag, but they were the size of jumbo jumbo shrimp. I enjoyed every bite. The server, who I had last time, was as helpful as ever and the place was a bit fuller this time so that's good to see. I can't wait to try the shrimp next time. read more

This is my new favorite Cajun spot! The quality of the seafood is good and the prices are reasonable to most Cajun restaurants. The clams are massive and one of my favorite things to order. The garlic noodles and fries are great accompanying sides. They soak up the yummy sauce from the seafood boil. The staff here are so friendly and welcoming. The last time we came, they asked us if we were celebrating any December birthdays. My husband's birthday was earlier that month. They checked his ID and gave him a complimentary cocktail on the house. The cocktails are strong! I love how this restaurant is close to home. Parking is easy in this plaza. read more

Cute restaurant with a marine decor. Staff is super friendly and do a wi Saul job of explaining the menu and specials. They also think about your spiciness level and make recommendations. Garlic noodles were delish and the seafood boil had really good flavor. We got medium spice level with torpedo sauce - a mix of all flavors. Good spiciness and garlic butter flavor. Shrimp is meaty and tender. The crab had a clog of amount of meat and cooked well. Their cocktails are also very good. There's also a cool jug of foamy hand cleaner that they bring at the end of the meal. Who knew cleaning hands would be fun! read more

Submarine Crab is a fun and very casual spot. It offers many different seafood options and has good flavor. My party got Combo #1 and it was enough for 3 people if you are not very hungry. The mild spice level is very mild and had no kick at all so highly recommended getting medium or spicy if you want a kick. The shrimp was meaty and the sausage and potatoes were tasty. I did not try the corn but my friends liked it. At the end of the meal, you get a fun and unique handwashing experience - like a volcano of soft soap that actually cleans your hands! The gloves and bibs provided were sufficient and easy to use. Currently, there is a happy new year offer where you get free white or red wine (1 glass per person). Our waitress was very friendly! And the restaurant was clean! :) read more

The Submarine Crab - Combo #1 - all shrimp - Cajun/Creole Near Me - Diamond Bar, California

Great new place for seafood boil! We ordered the Combo #3 and it fed four of us very well. Shrimp was plump and juicy, and the snow crab legs were cooked well - sweet and NOT too mushy or salty. Got the "torpedo" seasoning, which is everything mixed together, and the flavor was excellent! We also got medium spice level which had a really nice kick without overtaking the flavor. (If you don't like spice/heat, get no spice or mild.) Also tried the garlic noodles and they were delish! Added some of my crab to it - yum! There's a special right now where if your b-day is in January, you get any drink free - including cocktails! One of our group had a January b-day so the "Blue Lagoon" was chosen and enjoyed. My understanding is that this is every month. So I definitely plan to come back in my birthday month. Also want to come back and try the Cajun fried rice and the pasta. Service was excellent and the manager came over to check how things were tasting. Other servers were helpful with questions and kept our water refilled. There was also a cool way to "wash" our hands with a bubbling carafe of soap. The place is a good size and can accommodate larger parties by putting tables together. I would make a reservation for that. It's fairly new, but there was steady business. There's also a happy hour from 2-6, M-F. As more people learn about this place, I can see it getting busier. read more

The neighborhood was in need of a seafood boil spot and we are so excited that Submarine Crab has finally opened! We ordered Combo 3 and was the perfect amount of food for 4 adults. The shrimp and snow crab were delicious in the Torpedo sauce and our server even gave us a bowl of extra sauce on the side for dipping -- which I definitely used. I find the sauces at other spots way too salty but the sauce here is perfectly buttery and flavorful. The most unique thing about this spot is that the seafood combo is served in a large pot, making it a great destination for a family lunch or dinner. Lastly, I recommend the garlic noodles here. They are the best I've had from a seafood boil restaurant. read more

Casual restaurant with amazing food and employees! Everything we tried was delicious and I highly recommend coming here. The only downside is that parking may be difficult to find, as they're located in a busy shopping plaza. Tried a variety of items, including fresh oysters, Cajun fries, and their #2 combo (2 items/or two pounds of: shrimp, crawfish, mussels or clams $2 additional; and either snow crab legs, Dungeness crab legs or 2 lobster tails). We chose the torpedo sauce, which was a tasty combination of Cajun, garlic butter and lemon pepper - with medium spice level. The "mermaid" drink (passion fruit juice with Jelly & Crystal Boba) was served in a carafe with dry ice (very instagrammable/photogenic!) and could easily serve 2 people. Although a little more expensive than other other Cajun seafood places, the taste, quality, food presentation and great service is well worth it. read more

Dined here a few days before Christmas for my Dad and sister's bday. We did a reservation and the staff said they had some crowns and other decor for the celebrants which was really cool. Also they had a holiday/ Christmas special going on for each pot you order you spin a wheel for some free entries and or drinks! The experience for my family was great everybody enjoyed the experience and the food for a party of 7 we ordered two combo 3s with a mix of shrimp, lobsters and crabs. Also ordered some sides and drinks which was enough for all of us! The pots were very delicious one was torpedo sauce and the other was Cajun. They really filled up the pots with a ton of seafood! The lobster the shrimps, the snow crabs, the mussels were all flavorful and delicious. The staff here is very nice, friendly and very accommodating to our family. They helped take pictures and came to check on us constantly. The entire dining experience was great and my entire family had a great time and they loved the food! Thank you Submarine Crab!

This place has everything covered, a new restaurant has opened in Diamond Bar named Submarine Crab and I want to say it is amazingly delicious if you love seafood you will fall in love with this boil. Cane was here for dinner with a party of four and this place was filled with other patrons that almost we had no seats to sit in. But luckily we had one table. We ordered a dozen oysters they were nice and fresh. Got shrimp and mussels since they ran out of clams. But the sauce was on point. Maybe next time I will get the extra spicy flavor. If you check in through Yelp you also get a free hefty portion of garlic noodles. Which was so good. All my friends loved and enjoyed our nice dinner. Will come back to this new spot because the food is just overall good and fresh! read more

We celebrated my sister-in-law's birthday here on Valentine's Day, which is probably one of the busiest nights of the year, and the staff absolutely delivered. Even with how packed it was, everything ran smoothly. Our waitress, Jennie, was incredibly kind, attentive, and patient the entire night. She checked on us consistently without hovering and made sure we had everything we needed. You could tell she genuinely cared about giving us a good experience, even with the holiday rush. The food portions were also way bigger than expected. Every combo had more than enough food, and everything was flavorful and fresh. Definitely felt like we got great value for what we ordered.

Honestly I have such mixed reviews of this restaurant. I really want to like it more because they are fairly new and a small business, but I find it hard to want to come back with so many other food options nearby, so I have to honestly rate it a 3-3.5 star. Pros: I loved the aspiring magician's show at the end. His customer service was top notch and I really would have loved to give this place a 4 star for that. The head on shrimp was very good. The torpedo sauce was not bad and the Cajun fries had two dips. The potatoes were soft and the corn was well-seasoned in the sauce. I loved that they gave the sauce on the side for dipping, it was real convenient. I just wish there was more garlic haha. Ohh! The soap at the end was pretty cool too! The not-so-good: The fries were definitely over-fried, old, or double fried(?) most pieces were pretty hard. We love fries so we still had to kill it but definitely would not order again. The snow crab legs were really salty. We had to double check if it was the sauce or the crab, but it was 100% the crab. It was the most expensive of our bag so we had to finish it, but I would pass on this next time if I come back. It's a shame because we ordered the crab since it's in their name, but it was real disappointing for us. The peeled shrimp had a rubbery texture to it. I think this might just be how these shrimp are, but it was not very pleasant, I would HIGHLY recommend just getting the head on shrimp instead. It's more work but it'll taste MUCH better. Overall, I would come back if someone wanted to, but it would be hard for me to want to come back without any new changes to the menu. Also, the garlic noodle promotion for Yelp check in is no longer, but they said it may come back for Christmas time. Maybe if I come back, I'd try that along with my pound of head-on shrimp haha. read more
