of the 6 different ayce sushi places I've been to, K2 bistro had the best service and fantastic salmon nigiri (some salmon pieces tasted like 5 star sashimi). our water glasses were always full and the waiter was fast to pick up our order paper
however, most of the food was typical ayce quality, not fantastic but pleasing to eat, and there were no drinks on the ayce menu
the biggest downside was the room we were eating in. it was so COLD that my friend actually put on her jacket halfway through the meal (second floor dining room). perhaps the downstairs room is warmer, who knows. it also took awhile to get the bill but maybe that's cause we stayed until the end of lunchtime and there were bigger tables to clean up
pretty decent price, was 21$ after tip and tax for lunch (dinner is much more expensive!)
overall, the service was great, food was average (with some standouts), environment was subpar but the ambiance was good (it wasn't too loud or noisy).
as a huge fan of ayce sushi, I must say K2 is definitely a great option and now in my repertoire of lunch places.
