We were the first people in line today for the grand opening and the owner was so nice, she let us sit early and took our orders. We got to go orders because we had to leave but I ordered a vermicelli bowl and it was great, and my fiance got a banh mi which was also really good. We enjoyed them at a lake and the sandwich wasn't dry or super hard which was nice, and my vermicelli was perfect and I like how they put a lot of mint! read more

Pho 510 - Vietnamese Near Me - Castro Valley, California

Located on the second floor of the Castro Valley marketplace. Area felt spacious and the staff were very friendly. I had some doubts at first because their pho looked pricey, but it ended up being well worth it. My mom and I got a combination pho (the one without the ribeye) and a cold cut banh mi to share. The pho portion was massive. The broth was flavorful and aromatic, and one of the cuts of beef somehow tasted like bone marrow. It was fantastic. The banh mi was savory and crunchy. The creaminess of the pate and meats went perfectly with the refreshing vegetable fillings. I would definitely come here to eat again. read more

Delicious and super friendly. I like rice dishes. Last meal was curry chicken and it was great! 510 Pho us my husbands fav pho in the area

"Pho 5-10" (not 510) is on the 2nd Floor inside the Castro Valley Marketplace. Came here for dinner and we loved all of our dishes. Fried Chicken wings seasoned with garlic was a great starting dish. Pho with Rib Eye & Brisket came in a big bowl - the broth and meat were perfect. Pork Chop Rice Plate was tasty and delicious w 2 generous size pieces. Entire wait staff was friendly and accommodating. Beer and wine available... Free Parking in the back of the Castro Valley Marketplace. Can't wait to go back to try all the other dishes! read more

Just ate here and wasn't satisfied with the food or service 1. Host didn't have much of a personality. Lol it was just straight face no smile nothing lol Neither did anyone check on us in between 2. Pho tasted like it may have came from a packaging? The noodles were all stuck together and into a ball before I separated it all around 3. I mentioned about the 15% off happy hour on the appetizer but came the bill n they didn't take it off lol Okay good thing I looked Overall read more

I was excited to try this spot based on all the good reviews. Unfortunately I was disappointed. My friend ordered the chicken pho. They came back and said it was out but would be 10 minutes. It was more like 30. We were hungry and on a lunch break. They didn't offer us anything while we waited. A few spring rolls would've been nice. I had the regular pho P28 and the brisket was so chewy I could barely swallow it. It was like rubber. The soup was good but not worth the $20+ price tag. Also the herbs came after the soup came out so I had to wait again. Not worth the hype or the price. read more

Came here with my wife and the owner, Krystal, was so kind. She remembered my wife from her first visit, which was such a thoughtful touch. We started with the tofu spring rolls -- they were fresh, and the rice paper wrap wasn't chewy at all like some other places I've visited. The peanut sauce that came with them was really tasty. I had the house special pho, and it was fantastic. The broth was rich and flavorful, the noodles were just right, and the meats were all high quality and cooked perfectly. My wife ordered the shrimp banh mi, and it was one of the best we've had -- the bread was baked perfectly and everything inside came together really well. We also tried the tamarind drink, which was surprisingly good -- sweet, tangy, and the peanuts on top really tied it all together. The Thai iced tea was great too -- smooth and not overly sweet. All of the staff were very kind and helpful, which made the experience even better. Great food, warm service, and a welcoming vibe. We'll definitely be coming back often. read more

I was really excited to try Pho 510 because I used to frequent Le Cheval and found out that this was an offshoot. I decided to go on opening day and arrived at 10:45am 15 minutes before their 11am opening and was about the 20th person in line. Service was rough on Day 1 as it seemed like there really was 1 person doing EVERYTHING. I was finally able to get seated at 11:50am. It took another 30 minutes before my order was taken despite trying to flag down multiple service people with servers seemingly focusing on Togo orders. When the food finally arrived one of the orders was incorrect and which took some time to get sorted which it eventually did. Onto the food.... The 2 Pho's we ordered were solid and it was clear they used good, fresh and high quality ingredients. The Pho soup based was slightly on the sweeter side and star anise forward. The beef and assorted proteins were of very good quality. The overall amount of food is what I'd consider to be on the generous side. At $21 per bowl, this is what i would expect.. The Banh Mi was ok... For $13 which I would consider expensive the sandwich was light on meat and pate... Taste wise it was very solid. It took me 30 minutes of begging multiple people to get my bill which was unfortunately incorrect with them charging me for the $30 bowl of pho and excluding the Banh Mi altogether.. I figured it was a "wash" and was absolutely not going to try to have the fix it as I've been there well over 2 hours by this time.. Despite all the snafu's, the food is very solid and given that it was the 1st Day, the hiccups are understandable despite my frustration at the time. My advice to the establishment: 1. Have the Hostess at the front ONLY focus on seating the guests. The hostess whom I believe is also the owner was cleaning tables, serving food etc... while there were open tables and a line 25-35 deep which really made the wait painful. 2. Have a dedicated person take the Togo orders so these team members aren't ping ponging back and forth between seated guests and people waiting to order take out. (The server who was supposed to come back to my table took 3-4 orders from people who came WAY after me where i had to physically leave my seat to grab someone to eventually take my order). 3. Have clear cut guidelines as to what team members are responsible for. There was a few members trying to do everything and many doing seemingly very little.. Ultimately, this is a good add to Castro Valley. Pho 510 has a very robust menu with a lot of items I plan on trying in the future. I hope that the disjointed service I received one Day 1 is something they will focus on improving and eventually eliminating. Welcome to Castro Valley and I will you much success going forward! read more

The meat in the pho was actually the best I've ever had in pho. Hands down. They give a lot of meat and the meat was tender. The broth was very good. Me and the wife we're hesitant because it seems like the price was somewhat high for pho but we tried it today and concluded that the food is worth the price. I got the pho with the prime Angus beef and it was the best beef I've at a pho restaurant. The beef was just so tender. Egg rolls were super good and extra crispy. We'll be coming back to try the rest of the food. read more

Greeted so very nicely! Super attentive service, and a fairly large menu. Ambience is very lively with a gentle aroma of simmering broth, clean, and inviting. The Pho was so good not too salty very filling and it comes in one size! Shrimp spring rolls were so fresh and delicious! We will be back very often. read more

5/5 - Feels like home every single time I have to give Pho 510 the love it deserves. This place has become one of my absolute favorite spots, not just because the pho is incredible, but because of how genuinely warm and welcoming it feels. The broth here is honestly perfection -- rich, clean, and full of flavor without being heavy. You can taste the care that goes into it. The noodles are always fresh, the meat is tender, and the portions are exactly what you need on a cozy, comfort-food kind of day. But what really makes Pho 510 special is the owner. He has this amazing way of making everyone feel at home. Whether it's your first visit or your twentieth, he remembers you, checks in on you, and treats you like family. That kind of hospitality is rare, and it's a big part of why I keep coming back. If you want delicious pho and a place where you feel genuinely cared for, Pho 510 is the spot. I can't recommend it enough. read more

Really enjoyed their signature pho! I think it's Northern Viet style with super fatty meats to cook on the side in case you don't want the fatty broth on your pho. Generous portions and flavorful broth. We also had the spring rolls, which had a satisfying filling and good fry on the wrapper. Service was quick but they got pretty busy toward the end before we got the check. Can't wait to try more dishes next time. read more

Pho 510 - Grilled Steak with a order of side shrimps - Vietnamese Near Me - Castro Valley, California

Came here on a busy Sunday nite. The service started out great, but went downhill when there was a wait. We ordered 2 dishes plus an appetizer. My dish and the appetizer came out, but the other dish was forgotten. When I went up, the server just took off the forgotten dish and never even offered an explanation or compensation for time. The food was good, but not so much for me to out of my way. read more

I was really sad when Auntie 7 burnt down, that was our usual goto. But my sister, cousin and I decided to try Pho 510. And we were really impressed, the place is really clean, the food is clean and doesn't leave you feeling bloated from the salt and msg. I don't usually take my kids out for pho since I prefer the healthier versions I make at home, but 510 Pho is an exception. The restaurant is spotless with a very clean, open kitchen that gives you confidence in what you're eating. The pho broth is light, clean, and not overly salty--it tastes wholesome and healthy, which is rare when dining out. The atmosphere feels family-friendly, and I've even brought my girls here, which says a lot. The staff is warm and welcoming, and Crystal in particular always makes us feel at home with her kindness and genuine friendliness. Overall, 510 Pho is one of the few pho spots I truly trust for both quality and service. Highly recommend if you're looking for clean, flavorful pho in a comfortable setting. read more

I enjoyed the pho. The service was friendly and great. I also liked how the spring rolls didn't automatically have bean sprouts. This is commonly a dish I have to avoid because other places automatically add it. Also enjoyed the peanut sauce with it. Overall, I would come back. read more

Wow! I would give it 10 Stars! I tried the Pho Dac Biet fo $29!!! And yes, it is legit and worth the price! The broth is very, very flavorful! The quality of the meat choices and the generous amount was excellent. I would pay more for a great bowl of Pho than waste my money on mediocre Pho. A friend recommended this place and i am glad she did. The service was very good too. I will definitely come back here again. read more

Both my son and I had the pho tai and it was pretty mid for the $21 price tag.

Went there on Sunday, the day after the opening day with mom to try my luck. Mom doesn't eat beef and there was no option for vegetables broth or chicken broth. All descriptions of the broth have beef in it. It was a little disappointed on the options. I aimed to try pho and ban Chan. Ban Chan couldn't be accommodated since they were just opening. That was my second disappointment. The egg roll with taro was okay. The stir fried noodles section was definitely not their specialty and I couldn't recommend to try. The pho broth was good but I wouldn't wow on it. It is always room for improvement. Will I give another chance? Of course!! I will definitely have them chances since I haven't tried their specialty ban Chan and other dishes. The best part of this visit was meet and greet by crystal. She was very polite and her hospitality was way appreciated. Ambiance could get very loud due to neighbored restaurants and the crowds of the place itself. I always ended my review with "let's your taste bud be the judge. Please come and try them out" and yes thank you for being in this community read more

Pho 510 - Beef vermicelli bowl, soooo good - Vietnamese Near Me - Castro Valley, California

i must highlight our host, Krystal. she was so sweet and made the experience for us! she was so excited for us to try everything, because she genuinely believes in their dishes and the time they've taken to perfect their recipes. she mentioned the place is owned by her and two other ladies. banh mi 5-10 special: the STAR of the show. blown away. never had anything like this. while eating it, we were already thinking about the next time we can come back. (note: i'm joking with my verbiage and the "rude/ disrespect" has nothing to do with service) the whole time we kept saying "how rude of this brisket to be so good!!!" because it was soooo tender, juicy and flavorful. the bread was soft enough where it doesn't scrape the top of your mouth like other banh mi loaves usually do. topped off with dipping it in the Au Jus?! THE DISRESPECT, this sandwich has no business being so good!!! chicken wings 5-10: also a heavy hitter. wowow. we see why it's the special for their appetizers. when ordering it, Krystal nodded her head saying it's her favorite. i believed her every time, and not just her being bias since it's her restaurant. pho with rib eye & meat balls surprisingly... not the favorite of the spread! i will say the broth is less oily than most other places nearby. i feel like it's missing something, but that's personal preference. maybe because there was not as much onions & cilantro as i like (i asked for more to take home with my leftovers) & because i was getting full from eating everything else. also, was a bit confused that this came out last of all the dishes.. usually pho comes out SO quick, since their broths are at the ready in the back. pandan waffle for $3, my bf was hyped for this. we love a good green pandan waffle. watch, it's going to be the next fad after ube and matcha. krystal mentioned this is something she's been trying to perfect. that the underside is "ugly" LOL and she can't figure out how to make the look consistent. to us, it didn't matter. it was SO GOOD! she mentioned she likes to make her waffles softer and less of a crunchy texture, even though other people ask for it more toasty. she prides herself in it being more of a mochi type waffle, and a slight crisp on the outside. vietnamese coffee - strong and it shows in the color.. mind you that's coming from my viet coffee loving bf! Pho 5-10 has a very home-y feel that is comfortable, even though the restaurant is open in a public market versus a small restaurant as many other vietnamese spots. absolutely gorgeous decor! definitely on the pricier end, but we didn't mind supporting the business that deserves its stay here. please come try it out!! and meet krystal, the one with the warm smile and adorable dimples. she'll make sure you're taken care of :) read more

This is a little bit early to review, since they *just* opened. So, I think they're still working out some issues. I had a couple issues with their service, but nothing out of the ordinary for a place that just opened, in kind of a non-typical layout. But, the food, I would expect, should be close to what they should be serving even when they get their opening kinks out. And, I was not disappointed. The flavors are lighter than, say, Pho Auntie 7. More refined, possibly? Definitely good, but just hits in a little differently, and good to have choices depending on your mood, although I might end up at 5-10 just because it's closer. read more

Service was amazing. Krystal is a sweet heart. Food was amazing. Flavorful, fresh, and great portions. I love the comprehensive menu. By far my new go to spot for Vietnamese food in the area. It's always busy, but you never have to wait too long for your food. I have no idea how they do it! They've only been open for a week, but they have been able to service so many people. It's been packed every time we've come. The tamarind drink is so yummy. I highly recommend this spot - family friendly, casual, and very very authentic food. Love this place! read more

Didn't manage to grab any pictures but we ordered a chicken and beef pho and both were flavorful, rich, comforting, totally hit the spot. Tons of toppings provided that were fresh.

I'm giving a three-star review not because of the food, but due to an experience I noticed today. Around 2:00 pm on 2/8/26, I observed an employee in the restroom who appeared to leave without washing her hands after use, even though she was wearing gloves. She was wearing a tan cap. I recognized her as an employee because she was wearing a black T-shirt with your logo, and all staff in the restaurant were wearing the same shirt. I understand that gloves are used for safety, but handwashing is still an important part of maintaining good hygiene, especially in a food service environment. I'm sharing this out of concern and in hopes it can be addressed. The food itself is very good, and I enjoy eating here. One small additional note is that frequent check-ins from staff while customers are eating can sometimes feel a bit rushed. Overall, I appreciate the service and hope this feedback is helpful. read more

Very unorganized staff and long wait times. Unless this changes I do not see people wanting to return. One male server took our order and left us for 25 minutes to do other tasks then the same person came back and asked if we were waiting for our check. We never received any food at this point. Other tables around us also seemed to have been waiting 45min+ for their orders of Pho and other low-assembly time foods. My partner and I contemplated leaving multiple times because our food took so long coming out. Food was very underwhelming and under-portioned for the price. I had ordered the grilled pork vermicelli bowl and it was not bad, but it didn't taste anything worth the wait. The portion sizing was also very small. It filled me up only 1/3rd (I am a 105LB woman). The head female server at the front seemed to be the only one who had some semblance of how things are supposed to run, but unfortunately the rest of the team seemed to be struggling. Best of luck to her. Staff were friendly but I would rather I have food to eat read more

Review is for 09/21/2025 around 1:15 PM. 1. It's been 60+ minutes for appetizers (one order of spring rolls) to arrive. 2. The table of 4 sitting adjacent from the railing has just gotten their food after sitting at their table for at least an hour. 3. The folks here are friendly which earns their star. 4. The two tables behind me just got up and left after waiting for 35 minutes for their food. 5. This is more small town busy than Bay Area busy. They seriously need to make improvements or shut their doors after a few months. read more
