More of a 3.5. I've tried both a la carte and ayce sushi. I would say a la carte is the better deal. Alternatively if you like the variety in ayce, it may be more economical to get a few bento box orders so you can get tempura and a variety of rolls and/or "sashimi". The price of the ayce is comparable to sushi places with real meat/fish, and I feel kind of ripped off paying that same price for fake meat/fish which cost less.
Speaking of sashimi I was quite impressed by how close to the real thing this place got. The texture is like a firm jelly and they lay the sashimi on top of seaweed so some of the fishy taste latches on to the "sashimi". Their specialty rolls are also very good. In particular I recommend the super yam roll and the one with mango. Each roll is very sizable and are loaded with ingredients.
They also offer some chinese/thai dishes. I recommend anything that is fried and slathered with their sweet and sour. This ranges from fake chicken to bean curd slithers and all are delicious. Batter is super crispy and sweet and sour sauce reaches the perfect balance between the two tastes.
Overall great place to go with a vegetarian friend who's tired of the typical vegetarian fare!
