Korean indoor gas grill
I think the bottom unit is just a regular asian supermarket butane grill and you can buy the "attachment" plate on top separately. I've seen the whole package at Galleria and PAT, and any asian supermarket has the bottom if thats all you need.
It works great for hotpot and we use ours for camping and beach use, but we bring a cast iron pan instead of the korean style grill.
One of the pros is that you can do Korean style bbq at home. One of the cons is that even when well oiled, the food wants to stick and leave a residue. This chars and becomes somewhat difficult to cook on.
I bought mine in chinatown, Montreal, so you may wanna look in your chinatown, maybe Korean grocery.
