OZ IS AMAZING!!! We went last week for my boyfriend Jeffery's 22nd Bday. It's a little bit of a drive from Davis but it's TOTALLY worth it!!! Oz provides free parking and its really convenient. No Valet. For $17.99 ($18.99 on Friday and Saturday) you get endless trays of Bul-Go-Gi, Flank Steak, Chicken, Toro, Seasame Beef, and Beef Short Rib. All the meet comes served to you raw and marinated and you cook it fresh at the table! They also provide rice and ban-chan (small korean pickled side-dishes). Lettuce wraps don't come with your meal, but I recommend you spend the dollar or so to get them. Korean BBQ is traditionally eaten with grilled meat, rice, and korean-chili-paste wrapped in a lettuce wrap. They have a bar here, but the drinks are expensive and I don't recommend it.
On your birthday you get to spin the birthday wheel and you can get something for free! They also give you a small cake and the staff sings you Happy Birthday! :)
The service is pretty good - considering the fact that they always seem under-staffed. No complaints here. HIGHLY RECOMMENDED IF YOUR A MEAT LOVER!
