I like the concept of all you can eat when it comes to sushi... I can and have easily eaten 100s of dollars of sushi just on my own. The common problems with AYCE is the fish is either cheap, they limit the time and then serve too slow or to make the price affordable all they give you is rice. But since I am in the land of buffets and AYCEs I would give sushi another try for All-you-can eat.
Brian's Beach was the first on my list based on you lovely YELPers and a couple of other random sites I checked. The restaurant is pretty small with a couple of tables and a curved sushi bar. Seating is quick and food comes out FAST!! You can order ANYTHING on the menu for all you can eat including interesting appetizers and desserts.
The menu is not huge by sushi bar standards but is isn't too shabby either. Gems include Tuna Poke, Gyoza (dumplings), and standard fish (tuna, salmon, yellow tail), the sweet shrimp (with deep fried head) was tasty and the head was fried perfectly. The items I haven't enjoyed have been Uni (sea urchin) tasted way too fishy and squid (way too chewy). The rolls as a whole were not that great. Some had WAY too much rice and there wasn't a huge selection. Dessert was OK just your standard mochi, ice cream or cheesecake. Be aware there is a charge if you leave 3 or more pieces left on your plate (not too unreasonable).
Why 3 stars you may ask... well I would have given it 2.5 but that isn't a feature to yelp. I wrote this review based on two visits to this restaurant. It wasn't bad the price was OK and the service was quick. The problem I ran into (which haunts all AYCE places) is the amount of rice. As for my issues with the Uni... buyer beware when it comes to high end fish at low prices... that and I am an Uni snob.
I continue my quest for good AYCE sushi hoping there is a holy grail out there....
