Definitely my favorite AYCE sushi restaurant. Not so much for lunch as the menu is kinda limited and not as fresh, but I love it for dinner! Never had to wait longer than 10 minutes for a booth because I always make reservations. The line does get pretty huge, though. Especially on weekends.
The price is pretty good, like others mentioned. Around $14 for lunch and $24 for dinner. Sometimes it's fresher than other times but it's definitely never stale.
The service can be slow at times but 90% of the time, the place is so packed that they keep up with all their orders pretty well. Some of the waiters don't speak the greatest English so sometimes you'll either get something you didn't order, or like 10 pieces of tempura instead of 5. Not complaining though, I always manage to finish it.
I've been to Aji Sai about 50+ times. Absolutely love it. Definitely a regular there and the waiters/staff definitely treat my bf and I as regulars.
