No question about it, Demeris has good BBQ. They offer the usual variety of meats (brisket, links, ribs, chicken, turkey). The links are mediocre, but everything else is very tasty. Their sauce has a good flavor, although my girlfriend noticed it's a little thin. Their stuffed potatoes are enormous, packed with the meat of your choice, and come with a side of sauce.
There isn't much to the service portion, you go up to the counter and order, it usually only takes 3-4 minutes to get your plate.
There is a woman who works the cash register that acts as though she would rather jab knitting needles in her ears that place your order.
Pros: Good food, good prices
