I recently had the nigiri sushi combo at Oga's Japanese Cuisine in Natick, and thought it was fantastic. Instead of just having the same old maguro, sake, regular (cooked) ebi, some kind of white fish, and if you're lucky a piece of yellowtail, this combo had 10 pieces of really interesting fish including toro, ama ebi, kampachi, hiramasa, sea bass, red snapper, and scallop, to name a few. The fish was fresh, the rice was well-made, and overall I thought it was the best value and variety in sushi I'd had in the Boston area in years.
What sushi spots closer to downtown Boston have good combos like this? If the quality is good and it's not the same boring types of fish in most combos, I think this is one of the best ways to have a great sushi dinner for a good price. I.e., if you end up having to order all 10 types of nigiri that you want a la carte, you get 20 pieces which is too much to eat and also pricey. I guess basically what I'm looking for is an omakase experience downdown that is of decent quality and doesn't cost a fortune (the one at Oga's was 20-something).
