I've eaten here since their grand opening a few years back, usually getting take-out nowadays and occasionally sitting-in. This place is as good as it gets for AYCE sushi in this area (sorry not sorry Masa sushi/Ginza). Reasonable prices (where else are you going to get fresh sushi at $3/roll?), fast service and yummy food. Sometimes they skimp on eel but that's okay - just order more.
People complaining about the service obviously don't know what to expect when eating an Asian restaurant. Service is brisk, there's generally no up-selling and patrons shouldn't be expected to linger long after your meal. Eat and get out (not saying I ever felt rushed because I didn't). My measure of good service in an Asian restaurant is how quickly I'm acknowledged, take my order & bring my food. If you're looking for the waiter to ask how your day is going - you're in the wrong place lol. It can get pretty packed here during lunch/weekends so be prepared to wait!
Recommend: try the chicken yaki (fried udon noodles) and dynamite roll!
