At 8pm on a Friday night, Moira was shockingly quiet, only 4-5 tables filled in the restaurant. it suited us perfectly though. We sat at the sushi bar and were immediately attended to by a waiter and one of the chefs. Definite props on the service, they were attentive and helpful.
I was pretty excited to hear they had kona kampachi, so we started with two pieces of the kona, tuna sashimi and a shrimp tempura roll. The roll was fine, the tuna looked great, but it had that slightly chewy fat line in it (I really hate that... so disappointing) but the kona kampachi nigiri was so good we immediately ordered a sashimi plate of it. Really outstanding and generously sized pieces of it too. We followed that up with unagi nigiri which was fantastic.
Overall, I thought the sushi was very good - other than the tuna everything was spot-on how it's supposed to be. I really didn't think the prices were unreasonable (you want some sushi that isn't worth the prices, go to Pure in old town... oy vey), and the portions looked perfect to me. I really really hope that the tuna is better next time I go, though :(
Since a few people mentioned the chairs, I'll give you my opinion on them... Since we were at the sushi bar, we were on barstools. Once I was up on the chair I was very comfortable... it was just the getting up onto it, and off of it, IN A SKIRT, after a sake bomber, that was difficult :) You'll see what I mean if you go!
Note: I was disappointed that my usual Kirin was not available, but just had an Asahi instead... they had many asian beers I wasn't familiar with, maybe next time I'll be adventurous and try one of them....
