We walked in and the first impression was actually great--the waiting area is modern, clean, and inviting. They offer coffee and tea, and the menu presentation up front is clear and well done. However, things changed once we were seated. Even though the restaurant was only about 15% full, we waited around 7 minutes to be seated. Inside, the atmosphere felt completely different--older, worn chairs, no music, and menus that were wrinkled and falling apart on clipboards. Service was unfortunately lacking. After sitting for about 10 minutes without being acknowledged, my wife had to get up and find someone to take our order. There appeared to be 2-3 servers on with only about 10 customers (around 4 parties), so it was surprising. The food itself was decent, but not without issues. My bone-in rib was very chewy, and I wasn't given a knife. Water refills were also overlooked, with a few glasses sitting empty for a while. By the end, we had already boxed up our food and were ready to leave, but no one explained how to pay--we had to ask.

Tried to order a banh mi for lunch but it wasn't available, which was a bit disappointing. So we ended up getting the chicken fried rice, fried shrimp rolls, spring rolls, and a side of broth. The broth was very flavorful, one of the better ones I've had in the area. Spring rolls were a good size. The chicken fried rice was good, though the chicken itself was heavily seasoned (better suited for a rice plate) which made the fried rice a little on the saltier side. The main issue was with the shrimp rolls. We watched our server accidentally drop one, then bring us the plate with only four (out of five) without saying anything. We waited for her to acknowledge it or let us know a replacement was coming, but she didn't. It took a while to flag someone down, and they confirmed what happened and said they'd remake it. Accidents happen, but it would've been nice for the server to at least acknowledge it instead of acting like nothing happened. The replacement didn't come out until about 30+ minutes later. Overall the food was decent (though a bit on the pricier side for typical pho spot items), but the service could definitely be better.

Finally made it to Quan Ong Sau, and it absolutely lived up to the hype. Fresh noodles at no extra charge? Say no more. The beef was incredibly tender, the broth was rich and aromatic, and the ribs literally slid right off the bone. The combo rice plate was just as impressive--you can tell the pork chop was cooked to order, juicy and full of flavor. On top of the delicious food, the presentation was beautiful, the interior is modern and stylish, and the staff are genuinely warm and welcoming. Definitely a spot I'll be coming back to!

Bad customer service. The restaurant was extremely understaffed: one employee was making coffee, seating customers, handling checkout, and cleaning tables all at the same time. There were plenty of empty tables available, yet customers still could not be seated. We were first told the wait would be 10 minutes, then 15 minutes, but we ended up standing and waiting for over 30 minutes with no apology. There was no waitlist system or numbering; customers basically had to keep track themselves of who was first or second in line. In total, it took 45 minutes from the time we walked in just to place our order, and nearly an hour to receive our food, and the restaurant was not even full. Completely unacceptable. We understand the place being understaffed, but 2 out of the 3 staff members were dismissive, and no apology was ever offered for the terrible experience. If you can't hire enough staff and train them properly, then you shouldn't be in the restaurant business wasting people's time like this. Food: The Spicy Beef Noodle (Bun Bo Hue) was bland, flavorless. The noodles were way too soft and tasted like they had been cooked multiple times or cooked in batches and microwaved instead of freshly blanched. Couldn't even finish it. Also ordered beef short ribs. The portions were small and not worth the prices. These are Bellevue-level prices, but this is not Bellevue. Then we had to wait again at the register in order for the staff to be available so we could pay!!! Couldn't believe it! Definitely not coming back.

Came back for a 2nd visit! Tried a pork bahn mi this time and was very underwhelmed with the overall portion & size. It almost felt like a kid's sandwich. While it tasted good, the portion was very small for what you pay for. I would not get this again. Service was attentive and food came out as fast as it could, despite how busy it was there.

We were in the Everett area buying a car with my hubby and mother-in-law, and our dealer picked up food and drinks for us from Quán Ông Sáu such a great choice. We tried the grilled pork bánh mì, and it was packed with meat and super filling. The pork was flavorful, nicely grilled, and everything still tasted fresh even as takeout. Definitely no skimping here. The drinks were a highlight. The egg coffee was rich and creamy without being too sweet, and the ube coconut cloud was refreshing, lightly sweet, and so good. Perfect if you like unique coffee drinks. We didn't get to try the hot food yet, but I've heard their bún bò Huế is amazing and as a Vietnamese soup lover, that's already on my must-try list. Even as takeout, everything impressed us. Would absolutely come back if we're in the area again!

I really wanted to like Quan Ong Sau, but the experience was disappointing overall. The staff were genuinely kind and attentive, which honestly was the biggest highlight of the visit. Unfortunately, the food and execution didn't live up to expectations. About half the menu was unavailable, which is hard to understand, especially on a weekend at 6pm. Not having bún bò Huế at that time feels like a major miss. The egg rolls came out cold and were mostly taro with very little meat, which made them feel more filler than flavor. The pho broth was extremely bland, to the point where I had to drown it in sriracha just to get any depth of flavor. The one standout item was the ube coconut cloud. It was genuinely delicious, but at $8 it felt overpriced, especially since the cup was mostly ice. With so many strong Vietnamese options in the Seattle metro area, it's hard not to compare. Between the menu shortages and inconsistent food quality, I'm not sure how long this place can last as-is. They really need to get their act together if they want to survive in such a competitive food scene.

Plenty of table at lunch. Nice host. Water readily served. Nice big open seatings arrangement. $17 for a big bowl of Pho and $18 for com tam. Service is super slow but we are in no rush. Clean restrooms. Good Pho and com tam. Recommended

Fish sauce chicken wings had a blast of flavor that wakes up the palletes for the rest of the meal. The wings were huge, juicy, and fried to perfection The pho broth was very good! The fresh banh pho tasted like banh cuon rolled, noticeably fresh and chewy -- poured then sliced into noodle strands. The broth and banh pho outshined the wagyu steak slices. Egg coffee nicely done

Upon entering the establishment, it was very clean and welcoming. The restaurant was spacious with tons of tables for small and big party. It did not feel overly crowded as each tables has a good spacing between them. The customer service was really attentive, staff will check in on you numerous of times to make sure that your water is filled, order is ready and etc. The food was decently portioned for the price. You definitely get the bang for your buck here. The wings was perfectly caramelized with the fish sauce that was piping hot when it came out. The rice dish was perfectly seasoned and charred, and they give you plenty so that you don't leave starving or feeling like you're being ripped off. One only critique for the negative star is that as we were devouring the food, one item fell short that made the whole dish unpleasant was the scallion oil. This has never happened before but the chef was heavy handed with the salt so the rice tasted super salty as it was drizzled on the rice so that kind ruined the dish. My other pet peeve is the Google review, in exchange for the 10% discount. I didn't take the offer because I didn't want the review to be skewed but I guess those reviews should be taken with the grain of salt, as with the scallion oil. There's not many good Vietnamese selections in Everett that meets the food, service and ambiance standard but this place definitely meet all the standards and beyond. I would come back here if I'm in the area and totally recommend for you to try out.

I have been waiting for this place to open for several months and drove by today and saw that they are open. We were immediately met with smiling faces and a welcoming atmosphere and seated right away. This restaurant is clean and bright with plenty of seating. We ordered a chicken skewer appetizer, a combo meat and rice plate and a beef Pho. All tasted excellent and the portions were huge. They have a large menu with lots of options and we definitely plan to go back for more!

My family came here yesterday (Friday evening 6:30pm) for our mom's birthday. I was excited to try it out after looking at their website. Food is your typical Vietnamese offerings and was as expected. The space was big and spacious and parking was easy. The young "front" service staff were super nice, kind and obviously inexperienced but they really tried. They seem to also be very understaffed. We were extremely patient knowing this. Long wait on food. They ran out of chicken wings and the seafood pho (on a Friday evening main dinner hour). There were no utensils or napkins for one of our tables and we must've of asked for them on 3 different occasions. We eventually self-served and walked around to other tables to grab what we needed including condiments. We were not given any plates for our appetizer dishes so we ate on our napkins which we grabbed ourselves from a nearby counter. It was tough because while service was awful, you can see the staff struggling to keep up. It was such a mixed and awkward feeling. Like I want to like this place, but they really have a lot to work out. I personally won't be coming out all the way there again considering there are plenty decent Vietnamese restaurants around. My family still enjoyed their food and still might due to their proximity. 3 stars is for believing they can make improvements on the service portion of operations.

Since their opening I have come here no less than 10 times. Either myself or other in our party always get pho and it was surprising at first because it comes with a fresh noodle - which is a wide noodle with a bouncy texture - and to me it is better than the regular stick noodle. The brother is very rich in flavor and is one of the best I've tasted. Now they ask which noodle option you would like as some may be thrown off by the noodle, but I would recommend trying the fresh noodle option. Their portions are large! The pho does not leave me wanting more as I am an always satisfied/full whereas I am still a little snackish after other pho restaurants. They do not short on the meat. The rice dishes could most definitely feed 2. The drink menu at QOS is full of amazing drinks, I personally am a fan of coffee and I've tried every flavor. I am biased towards coconut flavoring so the pandan and coconut are my top two choices. The coconut comes with roasted coconut chips which adds a some crunchy texture to the rich mix of the coconut cream and the coffee, whereas the pandas is smooth and has the best flavor to me. The ube and egg are also very good. I always get two coffees when I come and eat here. One in the beginning and one at the end/to go. Service has been good, at times I have waited a little long for them to come take our order or to bring us an extra set of utensils but nothing to bring my review down. The ambience is nice, there is good spacing between tables and the natural lighting that comes in through the dining room is very nice and warm. All of the staff is friendly as well. This has become our go to pho spot and i do not see that changing anytime soon.
