apparently, the concept of cheap all you can eat korean bbq is catching on throughout k-town since the bbq business has been down due to the relatively recent mad cow disease scare. anyhow, i just ate at a restaurant called MANNA (on Olympic near Gramercy). For a set price of $14.99/person, they offer unlimited portion of four different types of meat: black pork samgyeopsal (uncured korean bacon), dwehji galbi (pork galbi- marinated in red sauce), galbi joomooluk (galbi without the bones- marinated), and chadolbekki (brisket- not marinated). quality of the meat was OK, nothing spectacular. i guess that's what you get for $15. you cook your own meat at your table like any other korean bbq place. if you want more meat, you ring the service bell like 50 times until somebody stops by and ask for more. also, they have extra food hiding in the kitchen and will not serve it to you unless you ask. so things you can ask for: egg soup (it's just steamed egg omelette/soup, but good), rice porridge and dwenjang jjigeh (soy bean (i think) soup- tastes better than it sounds).
overall, i say you get a good bang for your buck if you are an eater like me. (oh, another plus- they give you those rice wrappers to wrap your meat in)
