I've bought take out twice from Sushi Karu and both times it was great. Reasonably priced items that are fresh and tasty. Well worth it! Also, the lady at cash is extremely nice and does her best to make you feel welcome. I'd recommend this place in a heartbeat.
My only (small and easily overlooked) gripe is that restaurant is take out only and you can't dine in - but this makes sense as the place is tiny.
