Thank you Pho 510 for providing the best meal to help get over the bad virus going around to start 2026. 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. Picked up our order Togo but every table was taken inside. Thankful for this gem. Can't wait to try more when we are feeling better! read more

I had such a superb time I keep thinking of this restaurant and I look forward into coming back. Cody was so friendly and helpful to me. He was so kind and warm towards me. They had many vegetarian options. I had the vegetarian noodle soup with tofu and seasonal veggies. I told him it was delicious. I asked if the broth was also vegan? He said if it says vegan, it's really vegan. He also informed me that I could customize a dish, they are considerate of food allergies, and they would be happy to make me happy. The place was very clean, spacious yet cozy. I use a wheelchair, and I felt comfortable moving around. I was amazed at their huge bowls. I didn't finish my soup, and I was unable to fit what was left over in the container they gave me. I had such a great time, and I love that they had many vegetarian options. I love their huge portions. I highly recommend this restaurant especially since this became my favorite Vietnamese restaurant. read more

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

Top-notch service from Krystal! She was friendly, attentive, and made the whole dining experience feel special. The food here is excellent -- we had the pho dac biet and com tam (broken rice) and both were fresh, flavorful, and perfectly cooked. The restaurant is extremely clean. Their drinks are phenomenal too. My tamarind drink had the perfect balance of sour and sweet -- so refreshing! Highly recommend Pho 510 and will definitely be coming back! read more

First timer- Ordered chicken pho, brisket pho and grilled pork spring rolls for pick up- food was packed and ready on time. The place had all tables full which was a good sign. The broth was absolutely delicious! Noodles and veggies packed separately which is always great to avoid overcooked noodles. Spring rolls looked like I had made them myself -breaking apart LOL but the flavor was good. Would definitely go back for the hot pho soup! read more

Food was great portion size and the atmosphere was very cozy while still giving space for conversation. I completely forgot our servers name but he was great and on top of it . He made sure we had everything we needed to enjoy our pho. We also met crystal who is so warm and friendly. Overall , it's my new go to place for pho read more

Pho 510 - P31 and fried rice - Vietnamese Near Me - Castro Valley, California

The food here is really good. I got plain pho with beef broth and noodles, no meat, and the broth was absolutely delicious. My family got pho with meat and had no complaints. Someone else ordered the pork chops and loved them. The avocado smoothie is also super creamy and very yummy. Service is great and very welcoming. I forgot to take a picture of the food but here's a pic of smoothie and waffle read more

Eh it was good. Not as good as those expressed here. Was disappointed with my $8 "ice"loaded ice coffee. ShrimpS pho was basic....bring Auntie Pho back!!! read more

We had a prejudiced experience today. My family and I walked in. We were greeted just like everyone else, got seated with the menu and waited. 15 mins went by and the waiter said she will bring us water, we never got our water but the whole time they were catering to a certain demographic table even though we made several attempts to get their attention that we' were ready to place an order to no avail. They only acknowledged us after the fact they realized we were getting ready to walk out. read more

Aside from having comforting and yummy food, they also have the best and kindest servers. This is the only pho place where every server is smiling. Crystal is truly a gem! She always makes everyone feel comfortable. read more

Service was nice. It is located in the Castro valley marketplace top floor. The food was great but pricing is a bit high. Wanted to try it and did not disappoint in flavor. Wait time varies on how busy they are since the space is limited. It is a cute spot but a bit tight. read more

Very mediocre food for the price. Bought two vermicelli bowls for $17 each and had more lettuce than actual vermicelli. We waited about 30 minutes before receiving our food. The chicken and pork for each bowl was lukewarm, so we don't know why it took so long. Male waiter only checked up on us once and asked us if we were waiting for the check not knowing that we were waiting for our food even though HE took our order. We told him we were waiting on our food and noticed him talk to the back of the house, so he probably forgot to put in our order or the kitchen was slacking. Front of house lady was busting her ass off, so we know she's trying her best and that the place is relatively new. Kitchen assembly line and customer service could use more improvement possibly through more efficient food preparation and staff training. read more

The food is good, but very pricey compared to other Vietnamese restaurants. Located on the second floor of a marketplace type building. Service is attentive. I would come back if I'm in the Castro Valley area, and too lazy to drive to a place in San Leandro or Hayward. read more

Great addition to the pho scene in CV after Aunti Pho's closed. The broth is flavorful, proteins are fresh and while it's moderately expensive it doesn't break the bank. The fried chicken app was tasty and kid friendly. read more

I've been coming here since it opened. And I've slowly become a regular. As a broke college student, I still come back for their brisket and rare steak pho, lemon grass chicken with white rice, and egg rolls. The food and flavor is consistent, the service is consistent and welcoming, and the establishment is family friendly but also a place where you can bring all your friends. read more

The portion size for the pho is too small for the premium. For $26 after tips and tax, i got a bowl of noodles with 2 meatballs and 2 pieces of meats and some tendons. read more

Pho 510 is praiseworthy because they check all the boxes! They have mastered the broth which is the soul of the dish: rich, clean and savory! It is with appreciation and great joy to receive a bowl that is hot and stays hot, generous quality meat and perfectly cooked noodles. With these combo, you feel so satisfied and nourished afterwards. The consistency of their excellent food, customer service and cleanliness, "510"is a force to be reckoned with in the Pho industry. The warm and sweet hospitality from Huyen and her wonderful staff particularly Emily...we love 510 and can't wait for next time! read more

Crystal was the best! The food was fantastic, we will definitely be back! Grateful to have a new go-to pho place read more

Wife and I ate there twice, on a Friday night and at noon on a Monday. They were very busy on Friday night, the opening week. Monday at noon, no problem. Food was excellent both times. On Friday, I had CX76 (chicken stir-fry), a flavorful blend of ingredients and a good balance between chicken and veggies. Sauce was delicious. My wife had TC67 (Grilled Beef clay pot rice) and I was envious, it was very good. On Monday I had P27 (Pho 5-10 House Special) and it is indeed special. The rare rib-eye is succulent, melt-in-your-mouth meat-butter. Super good. Wife had C57 (Grilled Pork Combo Rice) which included a shrimp cake wrapped around a sugarcane, also yummy. She also ordered N104 (Coconut Pandan Waffle) which is more like a slightly sweet, waffle-shaped mochi rather than a light and crispy waffle. It is also super good, I definitely prefer this over the usual waffles. The benefit of being less busy on Monday is that we got to talk to the proprietress a bit, and she explained how she really likes the rib-eye for the pho and they struggled over whether to offer it or not since it is a bit more expensive than other ingredients. Spoiler: it's worth it. She also said she likes sweet things and was happy to be able to offer the pancakes. She says kids really like it was ice cream, so look forward to that in the future. We will be regulars here. read more

Food is great! Portions very generous. We've had the Pho and a brisket Banh mi. Ordered a couple times for takeout. Service is THE best around. Lady working there recognized me and told me about their November promotion free meal for children and elderly, we have a newborn so dine in is not an option yet but she sent a complimentary meal for the kids. Forever customer for their care and quality. read more

Refreshing, clean tasting, yummy, yummy! Good vibes, great food & friendly staff. Egg coffee is a real "pickmeup". Egg foam on top is a must try. Making a regular visit to this lovely environment. read more

Well my wife and I have been back a few times and I even brought my son who absolutely LOVES Vietnamese food. I absolutely love the Grilled Pork Chop plate and my wife likes to order the Vermicelli bowls. I will mention that the flavors very consistent I can always count on this place to serve a delicious and hot meal. We always get service with a smile and the entire staff is very friendly plus they are all very willing to answer any questions or help in any way! Our server always seems to have a wonderful smile with a welcoming manner. This time we got there before the dinner rush we could actually hear music playing in the background with the sound of a busy restaurant type of chatter. I really enjoy eating at this spot mostly because it is very family friendly. Great Job guys keep it up!!!!!!! read more

Was able to come here on nye to try out their food and it was so good ! Have to come here again !!

The food was so good. Lots of yummy veggies in the Pho. Vegetable broth is so good! I ordered P 41 and hubby ordered the X82 Combination stir fried noodles so much veggies, shrimp, chicken, pork. Loved it. Service was good and we came early and so busy but not crazy. Everyone is so nice. Definitely try it. You will be back. read more

Rating 4.4. Pho noodles were soft and in tasty deeper broth than others I have tried and I enjoyed that. Came little after 5 on Sat nite and was seated promptly but crowded by the time we left. Look forward to returning to trying rice dishes and appetizers as got full w the pho only read more

It was very good like it felt as if an auntie and grandma duo was cooking back there . The staff were very friendly and attentive as well love the decor just right and not over the top and lighting also . I had a great experience there. Recommend to all read more

Went in on Saturday night and Microaggressions started from the moment we arrived! Not going to get into it but to sum it up: horrible waiter, long waits and no follow up. Not coming back and even made Pho the first time at home to avoid places like this again. read more

The food is good but I will only order takeout from now on. They are busy but they have enough waiters, but they just don't know what they are doing. Everyone of them only take out 1 order of pho or rice at a time, so they need to walk back and forth to take out food for a table of 4, another waitress, only take out 2 cups of water at a time for a table that come after us. They need to buy a tray and serves more people/table at the same time. This is the slowest pho restaurant I ever been to. read more

Checked out this amazing restaurant in the market. Located on the 2nd floor. Everything was fresh from the food to the drinks. Delish avocado smoothie and Thai iced tea. Krystal was attentive and made sure we were taken care of. Thank you for the great customer service and we will definitely come back and recommend your restaurant to friends and family. read more

Service was great. My pho is okay. Broth seemed very mild. Too mild. We thought the Bun was missing too. Maybe just a bad night perhaps? Someday we'll give it one more try. read more

This place is so good!! Packed on a Saturday night. I had the broken rice plate and pho. Everything was delicious. May be the best pho around. Next time I want to try their egg coffee! The waitress is super sweet and friendly. We'll be back soon! read more

Delicious food. So grateful they are here. Their customer service is outstanding. Exceeded my expectations every time!

Best pho in town!! Very rich and flavorful broth! It is one of my husbands and I go to comfort meals. Friendly service, and shout out to Crystal, she is always so kind and patient. She goes above and beyond and elevates the experience. She's the best! Love this place. read more

They really take pho to a new level. Very rich broth. Rice plates are legit. And friendly service. Highly recommend

This is a new place kinda hidden inside the Market Place on Castro Valley Blvd., 2nd floor. We went there during their grand opening and then a few more times. Their soup in the Pho is exceptional, not like some other Vietnamese places where they're all MSG. Made friends with Crystal, the owner who seems to have a lot of good experience. Love the place, the food and the people. read more

It is located on the second floor of the market place. I had a chicken salad to go. It was a big portion and enough to feed two! The salad was fresh, crispy and delicious! I am looking forward to going back there and try more food! read more

Our experience at Pho 510 was fantastic! The portions were generous, the broth was flavorful, and the meat was high quality. We had the pleasure of meeting the owner, Crystal, who is incredibly sweet and welcoming. You can really tell she pours a lot of love and effort into every dish on the menu. We tried several items--the different pho noodle soups, a combo rice plate, steamed rice cakes, and the coconut pandan waffle. Everything was delicious, but the dessert stood out so much that we ended up ordering five waffles for four people! They were perfectly chewy, moist, and absolutely addictive. read more
