Udon Mugizo - San Mateo - San Mateo (CA)

3 /5 Eugene Chen: Generic udon place with prompt service and clean space. Standard options of beef, curry, and tonkotsu. Udon was on the softer side. Visited December 2025. ---- We had the ultimate Tonkotsu Delux and the Nabeyaki udon. The large portions were about the size of regular portions at similar places. The pork-based soup and the nabeyaki broth tasted fine, but nothing special. I appreciate the dried bonito powder on the side for the tonkotsu udon. It allowed a flavor change for the soup. Besides the sleek and modern interior, I found it hard to differentiate this place from Marugame in Stonestown. I actually prefer the doneness of the udon at Marugame. If you are craving udon in the area and there is no line, maybe give it a try. Its serviceable. The yelp wait list was nice. The service was prompt and cordial. I feel like they wasted the space near the bar.

4 /5 Raymond Ngu: It was a nearly empty Monday night. We waited a minute before being acknowledged by staff and seated. The interior is spacious and bright. We ordered takoyaki, karaage, tempura udon and mentai cream udon. Enjoyed the takoyaki and karaage, however the mentai cream udon was a little too salty, even before mixing in the mentaiko. I was unable to finish it due to saltiness. Portion size was good and could be shared between two people. We did have to flag down a waiter for water when it seemed like they forgot.

5 /5 Geetanjali Chugh: Almost my first time trying udon, and I absolutely loved it! We ordered the nabeyaki udon, and it was excellent. the broth was light yet full of flavor, and the udon noodles were cooked to perfection. The shrimp tempura that came with it was crispy and satisfying and not greasy at all. Would recommend this udon. We also tried the seiro mushi, which is a complete meal featuring steamed vegetables, unagi, tempura, and a mini udon. If you’re hungry, definitely go for this. The unagi is served with a sweet and umami sauce. While I usually don’t enjoy sweet flavors in savory dishes, I still found the overall dish to be worth trying. The service was friendly, attentive, and knowledgeable, making for a really pleasant dining experience. The portion size is generous. The only downside is the wait: be sure to sign up on Yelp to join the queue, as it can get busy. That said, for this level of quality, the wait is absolutely worth it.

5 /5 Bonnie Gleicher: Top-notch everything, from the udons to the veggie tempuras. Make sure you “add yourself to the Yelp waitlist” on your way here so that you’re ahead of the line. Doing this next time to beat the wait! Beef sukiyaki udon was so good, a tad too sweet but all good, and the noodles and gooey egg delicious. Their tonkatsu udon was also great and creamy, and I’m not a big fan of pork. Loved their pumpkin and mushroom tempura. If you like eel, get one of their sets for an insane deal, which comes with soup, veggies, rice, for a couple dollars more than the udon.

5 /5 Ziling Mai: This was my second time dining here. The first visit, we tried the Mentai Cream Udon and Curry Udon. They were both were super salty, which kind of threw me off. But this time, they totally redeemed themselves. The standout dish of the night was the Spinach Salmon Udon. I wasn’t sure what to expect, especially with the bright green color, but it didn’t taste like spinach at all. It actually reminded me more of a creamy pasta, and it was surprisingly really good. The service also made the experience even better. The host and waiter were super friendly and had a bunch of jokes that kept the vibe fun and light.
