I have eaten at the Pufferbelly many times. The building itself is pretty neat an old converted train station. The decor is eh, but still it is original enough to be exciting.
They have a wide variety of items on the menu. I really like the Bourbon Glazed porterhouse pork chop. It is amazing, and giant I might add. I have had many sandwiches and burgers there as well. Everything is usually pretty decent. Some things a bit on the bland side for me, but I tend to like spicy and heavy flavors so americana is sometimes too bland for me.
Service is always decent, maybe a bit inexperienced, but I have always been well taken care of. The average age of the guests is a bit older which sometimes adds to the dated feel.
It is a standbye of mine for a decent place, not great but decent. It is also one of the few places for a better place in Kent.
