All you can eat for about 100 Baht, depending on which place you patronize. And some are huge. You can also get a set-up delivered to your hose or for a party. At the restaurants the BBQ burner, a clay pot full of charcoal with a circular grill on top. The outside ring is indented to to hold water\soup and the center convex for meat and seafood. Once you see it it's as easy as how am I going to eat all this?. At home the pot of charcoal sits on the floor or on a table.
It is great for groups and kids love it because ice cream usually comes with the deal at the restaurants. All this and music too.
