All,
Inspired by this thread, I decided to pick up a few pieces of fish from the place I posted above and give this a try:
The salmon and ahi were awesome and like restaurant quality sashimi. The hamachi was mediocre, prob related to there only being one piece left which was prob a crappy piece nobody who knows about this stuff wanted. Overall A+ first effort. I don't think I'll be motivated enough to make sushi rice and rolls and other crap though. Seaweed salad and ginger from the fish market too.
