Very affordable, easy access, comfortable to order as someone who doesn't say a thing in Japanese. As located in the middle of Roppongi, they are used to dealing with non-Japanese customers (though they don't speak English very well). A convenient option as it's not too crowded whenever you go. Just order only what you can eat and leave.
My rating: 3.5
