More like a 4.5. Great place to eat if you're in the area. Not too great though if you're with a large group. I came here on a Saturday afternoon with my family after a trip to the aquarium and was seated immediately . Service was fantastic and fast. Our waitress poured our tea consistently throughout our lunch meal, and took time to explain each dish we ordered to us. I had the unagi don which was absolutely fantastic, and had plenty of eel. The rolls we ordered were very large and filling. The love boat (I believe it was called) was amazingly presented and had a large variety of sashimi and nigiri.
Nothing was outrageously priced either. No complaints from me. Definitely would come here again if I were in area.
