Gave Momo San a second try as they changed their lunch menu since their soft opening. The service was great, including the waitress and chefs.
I ordered the Aburi Momo Plate and the problem is the value of the dish. The two nigiri are cooked shrimp and albacore tuna, whereas the aburi are two cooked shrimp and two salmon... The pieces of maki were spiced gourd... Definitely not my cup of tea for 19$ if all I'm getting is cooked shrimp and gourd. I think I can boil shrimp myself :) Moreover, the sushi rice is cold which isn't too pleasant.
Overall, Momosan is a good option for sushi on Baldwin since the other sushi shops closed. The restaurant is nicely renovated. Just be warned of what you will get.
