I remember visiting Kayuga the day they opened and eating very tasty sushi. I've since gone back on a number of occasions and been just as impressed. The service is always very friendly and the restaurant has a nice vibe. The prices are also very reasonable. A great place for an intimate lunch with a friend or a cozy dinner with a date. It's located right off the green B line, so very conveniently located for BU students and allston dwellers.
