Don't be hesitant because its in a mall/hotel. Hit up Bar 10 or the 'fishery' downstairs for drinks first and then go for sushi.
Take a chance on the Sake, I was a first timer and enjoyed it with sushi better than a beer or wine. Staff was great.
I'd stay away from the Chef Specialty (Chef does a mix of sashimi and sushi based on your request) but the amount is minimal. Get the toro, half cooked/raw, great! You can get two Sushi/Sashi Deluxes for the same price as the Specialty.
A really, really great place. Makes you feel like you are dining outside of Boston as the decor is very trendy. The place was loud with music yet surprisingly romantic... Enjoy!
Pros: Food, Service, Unique
Cons: Locale, not quiet
