Came here again recently with a group of 6 and we had a great time! The service was great, he was polite, water and tea refills, came to check in on us etc. the food portions are great for lunch and the prices are excellent. I've never been here for dinner but I think the lunch specials are a win. The food is pretty good as well- everyone got chicken teriyaki and I got the chirashi bowl- comes with a gentoo serving of salad and standard miso.
I guess it's variable depending on which server you get- some can barely speak English and others are great.
Def give it a try!
