Woo Che is awesome! I just held my birthday there as a nice group outing. Unfortunately, they don't have any tables thatfit more than 6 at a time, so we werer split up, but the experience was good.
COnsidering that an order of kalbi or bulgolgi will set you back $15 easily at a typical Korean BBQ, paying %12.99 for lunch or $15.99 for dinner for all you can eat is a steal.
They have a cooked food section and a raw section that you cook yourself. As with most buffets, the hot food is only good when it's fresh. The really star of the show is all of the marinated meat that you grill at your table. It's really tasty and a lot of fun so Woo Che deserves a full 4 stars!
TIPS: They offer a come back next time free if you go on your birthday. Drinks are included in your buffet price and there is ice cream included for dessert too. These 3 facts weren't really publicized anywhere.
