We usually come here for their lunch specials with our extended families. We usually just get the bento box lunch specials as there are too many little kids in our families to do the "grill your own food" experience.
Lunch specials are dirt cheap, ranges from $5.99 to $8-9, comes with rice, bbq meat (chicken/pork/beef/salmon), a few cubes of fried tofu, bean sprouts and a milk tea or coffee. It is good value, however, the food is neither bad or good. It's mediocre. Service is consistently good and fast every time; we usually come for early lunch when the restaurant is not filled up yet.
We did the all you can eat grilling our own meat at dinner with friends once. It's standard just like all the other Korean BBQ places.
