I'm a fan and a regular but sometimes the service is hit or miss. Sitting at the bar is fine, but a couple of times finding your waiter\waitress when you're sitting at a table is ridiculous.
With that said, AYCE sushi is not as amazing as "regular" sushi places (i.e. Sushi Fever, I love Sushi, Sushi Loca, etc) but Oyshi is always consistent when it comes to quality and quantity. Definitely worth a trip if you're looking for good AYCE sushi.
