Both were superb. My final foray, alone, was a quick lunch on my way to a meeting. I had a seared sashimi grade ahi steak that could've easily served two. I took home leftovers and made a sandwich the next day. I wasn't able to try dessert, but the cheesecake seemed popular and looked promising.
Service is as efficient as can be with such a high volume of business.
Perhaps they could use another waiter during peak hours. Baby Beluga serves a limited selection of beer and a few wines not worth mentioning. Even though it's a long haul for many Tucsonans, those who make the trip to Baby Beluga will be rewarded with the bounty of the sea and that's no small feat in the Sonoran desert.
