I have been here numerous times as it is walking distance from my office, and one of our go-to places for a group lunch.
Never really that full, we always can get a table for four or six of us without much of a wait.
Inside is generally clean with nice decor (last time it smelled like wet mop though - yuk!) and service is decent enough. They are not exactly friendly, but are not rude, and are relatively attentive, though at times we have had to wait quite a while to get the bill - not great when you have to get back to work.
Two stars because over the last few visits the food has consistently been pretty blah. Hot food came out cold, sashimi came out frozen, and a few items from our AYCE order never arrived.
Biggest complaint is that a few of us kept getting stomach sick after eating here - not a good sign. After the last visit when all of us got ill, we made the decision to never return.
Yes the lunch AYCE is cheap, but not worth it when the food sucks and makes you sick.
