I pop in once in a while, and I always like to switch up my order. I've tried their Izakaya Original Champon, their Japanese Katsu Curry Rice, and, of course, they have a huge menu of sushi rollsβI've honestly enjoyed everything so far. The staff is usually pretty attentive, which is definitely a nice bonus.
Overview
Walking into Izakaya Mai at 212 2nd Ave, San Mateo, CA 94401, United States, feels a bit like stepping off a busy California street and into a neighborhood spot somewhere in Tokyo. Iβve eaten at plenty of Japanese restaurants over the years, from sushi counters to ramen shops, but this place leans hard into the izakaya spirit: casual, social, and built for sharing. The first time I came here was after a long workday, and the relaxed energy immediately did what itβs supposed to do-slow you down and make you hungry.
The menu is where the experience really starts to shine. Instead of overwhelming you with endless pages, it focuses on well-executed small plates, grilled items, and comfort dishes that pair easily with sake or beer. I still remember ordering the chicken karaage on my first visit, expecting something decent but familiar. What came out was crisp on the outside, juicy inside, and seasoned in a way that reminded me of how Japanese chefs rely on balance rather than heavy sauces. Itβs a small detail, but itβs one of those moments where you can tell the kitchen knows exactly what itβs doing.
One thing I appreciate as someone who pays attention to food trends is how closely the menu reflects traditional izakaya cooking methods. According to data from the Japanese Ministry of Agriculture, classic izakaya dishes rely heavily on grilling, light frying, and fermentation-based seasonings like miso and soy sauce. You can taste that influence here, especially in the grilled skewers and savory plates meant to be shared. Itβs not fusion for the sake of novelty; itβs respectful, grounded cooking.
The process behind the food feels intentional. On a later visit, I sat close enough to the open kitchen to watch the flow during dinner rush. Orders moved fast, but nothing looked rushed. Skewers were turned carefully, plates wiped before heading out, and staff communicated clearly. That kind of rhythm doesnβt happen by accident. Restaurants that last usually develop systems that balance speed with consistency, and this place clearly has one.
Reviews around San Mateo often mention how reliable the food is, and Iβd agree with that. Iβve brought friends here who range from Japanese food obsessives to people who mostly know sushi rolls, and everyone finds something they like. One friend who rarely eats meat ended up loving the vegetable tempura, commenting that it wasnβt greasy or heavy. That aligns with what food science research has shown for years: lighter batter and proper oil temperature significantly reduce oil absorption, improving both texture and flavor.
Service plays a big role in why people keep coming back. The staff has always been friendly without being overbearing, happy to explain menu items or suggest pairings. On one visit, a server recommended a dry sake that cut perfectly through richer dishes, which made the meal feel more thought-out than a standard dinner. That kind of guidance builds trust, especially for diners who may not be familiar with izakaya-style dining.
As for the location, being right on 2nd Avenue makes it easy to drop in for a casual dinner or a late bite. Parking can be a little tight during peak hours, which is pretty typical for downtown San Mateo, so thatβs worth planning around. Aside from that, the space itself feels warm and inviting, with just enough background noise to feel lively without being overwhelming.
No restaurant is perfect, and during especially busy nights, wait times can stretch a bit longer than expected. Still, the consistency of the food and the overall experience make it worth it. For anyone looking for a place where the menu, atmosphere, and service come together naturally, this spot delivers in a way that feels genuine rather than forced.

Longstanding Izakaya restaurant located in downtown San Mateo. Surprisingly large menu of grill meats, fried tapas, curry rice bowls, nigiri, and lots of sushi rolls. Good casual place to hang out with friends. Fast and efficient service. Parking takes some time to find, but several parking lots within a 5 minute walk.
It's like a dive bar & a Japanese spot had a kid. The service is amazing, no frills type of joint. Food was amazing, can't go wrong with anything you order here. Got the chicken teriyaki as a app (even though I don't like thigh meat, this was delicious), lion king is my favorite roll here and don't skip the Yaki Udon.
Had dinner at Izakaya Mai and really enjoyed it! Itβs a cozy, casual spot with a huge menu and a casual vibe. Service was friendly and efficient.
First time coming, loved the food! good customer service. Planning to come again.
