Fat Matt's, on Peidmont Road, is good, and probably won't make you sick. I had what I always do, the Chopped Pork Sandwich for 3.95 and a side on Rum Baked Beans and a glass, which turns into three, of lemonade. It is important to notify the kidneys before drinking three glasses lemonade from Fat Matt's; they hate suprises.
The Sandwich is served on some sort of roll. As for the sauce it is vinegar based and just spicy enough (though too spicy for some, especially if you lack a gall bladder) and it has enough a sweet kick to confuse the taste buds.
The portions are decent, and the meat is good, not low quality. And sometimes they give you free pie.
