I love this place, great lunch spot and for dinner too. For lunch you can keep it light with just a soup so you don't pass out later in the day. For dinner you can get soup plus some gyoza or fried rice (which is the bomb, I love it here)
A new thing which is not on the menu is that you can get a mix of the Tonkatsu and the Shoyu broth, that's what I get. In addition, I always add corn and chopped onion, and an egg if I'm in the mood.
Server's are very friendly, and they work very fast and efficient. It's not a place where you're gonna chill for 3 hours and hang out, the place is small so people are in and out pretty fast.
A little side note: They have cans of Japanese iced tea which I had in Japan and never had in the US until coming here. I love that!
