We loved the ambiance and vibe of O Sea so much that we came back for happy hour. We loved the Pinkies Up wine. The waitstaff greeted us with iced waters immediately upon sitting down. We tried the crispy rice tuna and the spicy shrimp. Both items were super flavorful and delicious! We love this local HH spot and will be coming here often. read more

Food was pretty good for their happy hour for small bites! we came in to get the happy hour oysters and the crispy tuna rice, and the oysters of the day were a bit on the salty side, but it was fine since oysters tend to have different flavors depending on where they come from; the oysters were shucked clean though which I enjoyed and it also came with their own house made cocktail sauce and mignonette. The crispy tuna rice was flavorful and they were not shy with the tuna portioning! Flavors were great and fresh. Service was good and lots of staff asked us how we were going through the whole time. Ambiance was very nice! Super aesthetic, clean, rustic, and beachy vibes...made me feel like I was beachside the whole time. read more

O Sea in O.C. Modern, neat vibe and super fresh seafood. Portions were generous and everything tasted great. Only downside: our cioppino bowl was chipped and the utensils felt a bit old. Service was friendly but multiple servers checked in a few times and asked same questions, which made it a little hard to keep the conversation going. So I landed on 4 stars instead of 5 stars. read more

***Service*** 3/5 - Waitress would just come by and ask if everything was ok for the sake of asking without really paying attention to the table. Like we needed water and before we could tell her, she had already walked away. ***Ambiance*** 4/5 - standard cute little place ***Food*** 1/5 - We ordered. 1. Calamari - was good 5/5 flavor, texture, temperature, all there 2. Crab cake w/ Thai slaw - 2.5/5 crab cake was mediocre, temperature was warm... and there's nothing Thai about the Thai slaw... Just cuz they threw a few pieces of fried garlic on there don't mean it's Thai. The flavor was not Thai...I don't even know where they came up with that idea 3. Tuna Poke blood orange w/ taro chips - gave us a few pieces of tuna... not sure they know how to even cut the fish... it was stringy... the blood orange taste over powered the tuna. The flavor profile of the dishes is not well balanced. It is missing a bit of saltines and tanginess. It was overall way too sweet. 4. Cioppino - 2.5/5 seafood was fresh but the flavor was meh. it's basically a bunch of seafood and tomato soup. 5. Scallops - cooked well, fresh, but it was way too salty, yogurt and all other stuff overpowered the freshness of the scallops. Wasted the scallops ‍ 6. Fish & chips - fries was good, I mean it's hard to not make bad fries... but the fish... I don't know if they chose to be lazy or are they trying to be special but the fact that they threw a whole damn fish into the fryer and to serve it to you on the plate was the worst idea ever because it gets so soggy by the time you eat it. On top of that they didn't even marinate it so there was no flavor to the fish at all. **price** for the price of this place, I would expect better for than this. So I would def not recommend this place to anyone. read more

O Sea - Wild Washington Cod Fish & Chips - Seafood Near Me - Orange, California

I came here with my family for a birthday lunch and the food here is always great and very fresh! We made a reservation and we were seated pretty quickly. We were seated outside and the only reason why I would take away a star is because the service was a bit slow. It took almost an hour for our food to arrive. However, the food was delicious. My favorite was the cioppino. It contained a bunch of different seafood like mussels, shrimps, and fish. The oysters were also very fresh and sweet. The inside of the restaurant was decorated very nicely with Christmas decorations. read more

I was really excited to try this spot because I had heard good things and the name's pun is great (get it?). The interior is really gorgeous and welcoming. From the Fall menu, I decided to try the Farmed Atlantic Salmon Ceviche, the Spicy Wild Tahitian Albacore Tuna on Crispy Rice and both were so good! The portions were much bigger than I expected. For dessert, my server recommended to me the Panna Cotta of Coconut & Kaffir Lime and I loved it! read more

Absolutely amazing. We came here last minute and was able to make a reservation on the day of. It was fantastic, from the ambiance to the service to the exquisite meal. Price is reasonable for seafood in OC. We started off with the burrata with nuts and honey and they all complemented each other so well with every bite. Our main entree was the salmon avocado salad and the cod with veggies and sweet potato. The salmon was cooked very well. The cod mixed with the sauce was heaven. Cooked so well and flavored even better. We had no leftovers. read more

Great place for happy hour!! We celebrated a birthday here on Labor Day (normally closed Mondays but they were open for the holiday and honored happy hour/their lunch special). We arrived around 2pm (HH is 2-5) and our party of 5 was seated right away. The place is really cute inside with cute table set ups and menus. The table is a little narrow so it felt cramped sometimes, but not too big of a deal. Their oysters that day were sooo good! Very fresh and yummy tasting. They served them with vinegar and cocktail sauce. We ordered all of the items on the HH menu except for the burger. The mussels were my favorite of the appetizers, then the fried shrimp (the fries are very good!), and last the tuna on crispy rice (definitely wasn't bad but it was my least favorite of the 3). I ordered their lunch special which included 2 items for $20. I picked the salmon skin hand roll and the strawberry fields salad with cod (cod cost an extra $10). I wasn't very impressed with this, the hand roll was very small and barely had any salmon skin in it. The salad was okay, but I actually thought it came with a salad and tacos, not just one. If I got that again then I would go with the tacos instead. Wine is half off during HH so we got 2 bottles of the orange wine, so good! Our waiter was really sweet and brought out the Thai iced tea blondie topped with vanilla ice cream for the birthday girl. We were very impressed by this dessert, it was really tasty! Overall a nice experience, good for birthdays or cute date. I'm already planning on coming back to celebrate another friend's birthday! read more

Wonderful Sunday lunch at O Sea. Very calm and peaceful restaurant. Not loud and busy like most. The food was excellent. Loved everything we ordered especially the tuna with crispy rice. Perfect crunch. The mussels Thai sauce was amazing and great to dip your bread in and fries too! The fish and chips were excellent too. Light, flaky and crispy fish perfectly paired with tasty tartar sauce and refreshing cucumbers. Definitely want to come back and try other dishes. read more

I enjoyed the atmosphere and the food. The service by Alyse was superb. There is mostly seafood. I had the hot shrimp which is good but I think next time I would have fish and chips that was the choice of one of our friends. The hot shrimp are breaded and seasoned and pleasantly spiced. They were not too hot. They allow you to bring wine and no corkage as long as you offer one glass to another patron. Really cool idea and we mad a couple people happy. I don't like clams and mussels that much but others in our party really enjoyed them. My clam chowder soup was good. Nice location in old town orange. read more

The food here is super interesting and well thought out and well executed. I'm a huge foodie and will definitely be honest about sub par food. Nothing to complain about here though. I ordere 4 different things and it all tasted amazing. The interior is nice and bright. Staff is friendly and accommodating. And the prices felt fair. Would definitely eat here again! read more

Wow! Is how I am feeling right now. We have been wanting to try the place for a while now. What better time to try it than during Orange County restaurant week. We had reservations at 6pm today. We arrived and it was already full only about two tables were empty. We got seated right away. We went with the dinner menu that was advertised for restaurant week. We shared all of the dishes. For starters we had the hand roll with crispy salmon skin and the o sea "Chowdah" New England style. For main entree we chose the Sweet and spicy Cioppino and the New England lobster roll and for dessert we went with the two choice they had which were , Thai milk blonde sundae and the chocolate bread pudding. For drinks I had the Adventurous red wine flight and my husband had a Mexican lager beer. Everything was delicious and I can't believe we hadn't tried this place sooner. The chowder was so light and not rich at all but had all components of a good chowder. The hand roll was different in a good way, I wish it were bigger so I could have had more. Now let's talk the main dishes, the cioppino was amazing ! It had mussels, clams, fish , shrimp and calamari. The sauce was light but very tasty and it had the right amount of sauce to dip the four slices of toast that come with it. The lobster roll was also so good , lots of lobster meat and the roll was so soft and the right amount of butter. It was served with fries that were also good. Now to the great finale the desserts , we both were left wanting more of them. They were not overly sweet they were just perfect! All I can say is that if you haven't tried O Sea yet , go and try them out. You will not be disappointed. Keep up the great job! I will be back to try some more of the delicious food options. read more

We had a great night at O Sea! Our party of 6 got together to celebrate Mother's Day here, enjoying great company, some good food and excellent service. Our server guided us through the things we needed to know and was so attentive the entire night. And she went the extra mile too. When my little guy got a bit antsy, she found some paper for him to occupy himself with. Some of the food was awesome, some was just ok and one thing was so-so because it wasn't served the way it was supposed to. Here are the details so I'll remember how to order next time: ***The not so great: We ordered the special which was a white fish put in a green salsa. The salsa was not very tasty and super disappointing. My MIL chose a different special which featured Cod with butternut squash and that was AMAZING. ***The GREAT: I had a handroll with Albacore tuna that was awesome! We also had the most delicious oysters with just the right accoutrements. We added bread and butter where their butter had a bit of kosher salt on the top...YUM and totally worth the $4.95 for a tiny plate. ***The Could Have Maybe Been Great: We ordered the crispy Oaxacan Hot Shrimp which was plain fried shrimp, nothing special. Turns out it was supposed to be tossed in a guajillo & arbol chili oil which our server brought out after we asked, when we had one shrimp left. We tried it and the tiny bite I had seemed to be much more special. We did love the ambiance of the restaurant and the area in general. We had all forgotten how cute the Orange Circle area is and how packed with great restaurants it is. We'll be back and maybe for Happy Hour which is 2-5 on weekdays. Their Spicy Tahitian Albacore Tuna on Crispy rice is there along with the Oaxacan Hot Shrimp hopefully made the way the menu implies! read more

Was looking for a place for a late lunch near Old Town Orange and noticed that O Sea had a happy hour menu that starts at 2pm so it only made sense to come here. There's a public parking lot behind the restaurant which was perfect. The restaurant was so nice and airy. Loved the ambiance! Onto the food, I ordered half a dozen of their HH oysters which were the sweet minters. Also ordered the HH mussels (spicy), HH shrimp, and the salmon ceviche and a cup of clam chowder off their regular menu. All of the food was really good and the seafood tasted fresh. The sweet minter oysters were small and didn't have much body to them but I didn't expect much from happy hour pricing. The clam chowder was a little thin and tasted more like a bacon and potato soup with 3 clams on top. The salmon ceviche didn't have much flavor and bite to them like I would expect from a ceviche. The taro chips they came with were really nice and crunchy though! Now onto the standouts. The HH crispy hot shrimp were so plump and juicy, with a little smoky kick to them. The fries that it came with were perfectly crispy. The mussels were also plump and meaty and the coconutty broth it was cooked in was divine! My friend and I were sopping all of that light but savory broth with our bread. Service was great. Our waiter came by a couple of times to check up on us. Granted, there weren't any other tables that they were waiting on (since the other few tables were already done with their food). Overall, I was very pleased with my meal and all the fresh seafood. Would definitely be back for happy hour! read more

What a charming little restaurant. We truly enjoyed the atmosphere--inviting, cozy, and full of character. The food itself wasn't quite everything we had hoped for, but the service more than made up for it. The staff were incredibly friendly and attentive, which really elevated the experience. What stood out most to me was the attention to detail. I even noticed an employee carefully cleaning the planter at the entrance. Small gestures like that show just how much pride and care they put into maintaining the restaurant, and it absolutely carries through into the overall ambience. It's the kind of thoughtfulness that leaves a lasting impression. read more

We really enjoyed our night out for dinner here! We went as a family of 4 and they were super accommodating and gave us a highchair for our toddler and space to park our stroller for our baby. Here's what we tried: Daily oysters (barcat, minter sweet, Kumamoto) These were all really good! Not cheap though so I recommend coming for happy hour (I think 2-5pm) Wild eastern sea scallop aguachile 'negro' This was the best thing we had! Flavors were nice and bright and the scallops were soooo good and luscious. Pairing them with the taro chips was perfection. O sea chowdah This was slightly too salty but it was very flavorful! The clams in there were yummy. Two grilled fish tacos market plate We chose the cod - wasn't my favorite dish (prefer a fish that tastes more buttery and soft or maybe a fried fish would've been better). The rice and beans were a no go :( no flavor at all. Steamed PEI mussels These were really good! I feel like a lot of restaurants overcook their mussels but not here :)! The fries it comes with are also really bomb. Grilled cheese For the little one - the thick cut bread was yummy but a pretty basic dish (I guess all kids menu stuff is pretty simple haha) Would recommend!!! read more

Thank you Yelp for steering me to a fantastic spot that I never would have stumbled upon without yelp's help due to some major road closures in downtown Orange that needed to be navigated around. What a challenge for these businesses! Everything was fresh, tasty, and seasoned just enough to be flavorful without going overboard. Those beans with the Two Tacos almost tasted molé level seasoned while sitting being balanced enough to not be overboard. The Washington Cod & Fries... never had a crispier crunch on a batter than this, while still keeping the fish inside flakey fresh and perfectly cooked. The carrot cake? Fuhgettabput it... shared by two makes it a perfect ending treat without needing to be rolled out the door,.. or just walk in and have that with a cuppa coffee. read more

I came here for a lunch with my boss, which was a nice option in the Orange Circle. First of all, the atmosphere and aesthetics is airy and beautiful. We both opted for the Power Lunch Picks that gives you two choices for $21.95. I chose the Tuna Poke and Two Fish Tacos. You have your choice of fish and tortillas for the tacos as well, which I got cod and flour. Although my boss had ordered a drink, they completely forgot and it never came. It was even charged on the bill, which we had to ask to remove. For the food itself, the flavor is good but the dishes are so minimal. The poke had literally 5-6 pieces of fish with some taro chips. The fish tacos are presented nicely, but also not filling. I left quite unsatisfied and ended up making food at home. Decor and vibes on points, but value of food wasn't worth. The customer service was a bit lacking when we were trying to order or ask about our drink. Overall, glad I tried but won't be coming back. read more

Great place to come for happy hour oysters. They were pretty fresh and delicious. Interior is modern and gorgeous. Service was fine. My complaint is about the happy hour salmon ceviche.

O Sea - Happy hour oysters - Seafood Near Me - Orange, California

Whenever we travel, we look for good seafood restaurants and O Sea was one on my list! I made a reservation on Open Table. We ordered the fried calamari which was very tasty and crispy, the fish tacos and the Lean and Mean Plate! Hubby has his mind on fish tacos whenever we travel but he is used to the Mexican version which isn't as healthy as the ones he had tonight! He had the two fish tacos, one with one ono and one cod. As for me I ordered the lean and mean plate as I try to eat healthy whenever I can and whenever I'm traveling. So I had the cod which was perfect and it comes with a big green mixed salad. Parking was a bit tricky as it was dark and rainy but we found one a block and half and we weren't familiar with the area. Otherwise, we would have parked in the public parking lot. Service was attentive and friendly and a relaxing casual ambience in the restaurant. read more

We've been here twice now. First, they have a great reputation- I heard reviews from friends who have tried them during restaurant week and we've seen large crowds every time we walk past on visits to old town orange circle. Their dishes are crafted to perfection. I tried one oyster and the presentation was just immaculate- literally felt like it's a Michelin dish with how detailed it came out. We have also tried the strawberry salad, Washington cod fish and chips, and poke bowl. Their fish and chips is EPIC. Crispy, and comes with amazing sauces and lemon. They have an amazingly spicy habanero sauce that is top notch in flavor and spiciness.. try it with caution but so good to dip into when you order the fish and chips. They're super attentive and also have the most amazing venue. We are huge fans! read more

O Sea - One oyster for me ! - Seafood Near Me - Orange, California

This restaurant is super cute for a date, with modern touches and a nautical vibe. You can make reservations on OpenTable, but it is so spacious inside that you probably don't need to! We came for happy hour on a Friday at 2pm and got seated immediately. The happy hour deals and options are pretty good. I also recommend coming for lunch on a Monday-Friday from 11:30AM-4:00PM and getting the "power lunch picks". Service was great throughout our meal. :) 1) Spicy albacore tuna on crispy rice 3/5 2) Tuna poke: I loveee the taro chips! The poke was a little oily, though. 3/5 3) Mahi mahi fish tacos: You can pick corn or flour tortillas. Not the best tacos I've had, didn't have much flavor. 3/5 4) Salmon O Sea burrito: Great flavor, but came apart and was leaking the juices! 4/5 read more

Cute small restaurant in Orange. Ordered the calamari, octopus à la plancha, oysters and the crispy Oaxacan hot shrimp. I was expecting elevated Mexican fusion seafood flavors suggested by some of the menu language but left disappointed. No complaints on the service, just the flavors and confusing "fusion" menu. The hot shrimp, tasted good but more like buffalo wings. They weren't spicy at all. They also looked like buffalo wings in color which didn't help their case. The shrimp though were large in size and a good snack. The octopus was okay and had very crispy potato cubes COVERED in pesto underneath which was a confusing concept if thinking elevated Mexican but beautifully plated I'll give it that. The oysters were okay. I think that's more on the variety offered and personal preference. Plump something and I can't recall the other kind but they were okay for me. Maybe I'll like the next offering. As for the calamari, it was not memorable outside of the Oaxacan chili oil. If I were to go again, I'd probably take someone who can't handle spicy flavors but want a safe choice of fresh seafood meal in a cute place with familiar easy on the palate flavors. Truthfully speaking though, I don't think I'd go back on my own accord. It was not what I was looking for and I left unfulfilled. read more

Whenever we come to Old Town Orange, we are sure to stop and eat here. We came to town to walk around and stopped in for dinner. You can ALWAYS count on seeing the owner here. He greets you and sits you down. Super nice and stays quick to say hi. We started with the Crispy Rice. Yummy! The rice crisp was perfect and spicy tuna flavorful. I had the mahi-mahi tacos and they were tasty. My favorite part was the sauce and cucumbers. Great portion and filling with black beans and rice. My hubby had a garden salad with cod and he too said it was tasty, cooked well and filling. The restrooms are always really clean, the temperature is perfect! Not too cold and I'm never hot, which typically happens to me at restaurants. The place is always picture perfect too. If you're a wine lover, they got you!!!
