I've been going to Goyemon for quite some time now and I love how fresh and good the quality the fish is. The environment is very nice and the restaurant is well maintained. We were sat down very quickly, which is rare because the place is usually jam packed. I went at 9pm and the hostess allowed us to choose our seat.
The waitress was very attentive and refilled our drink cups. We didn't do all you can eat this time but I was very satisfied with I ordered (Sunrise, dragon roll, pastel, and edamame).
I gave it a four stars due to the fact that it's an awesome restaurant but sometimes wait times are just crazy long and like all sushi places, it's tiny. I just happened to get lucky this time around. I guess it just depends on the time you go because they do serve until 2am.
