If you are smelling something bad in a restaurant it is time to leave.  A little research would have turned up numerous bad reviews and saved you the gross out.  If you can smell it then the restaurant is nasty and should be avoided.  Often the restaurant is nasty and you cant smell it so if you do, get moving.  Some restaurants allow a good smell to lure business.  Ever walked by a coffee shop and smelled that good coffee?  How about that pastry shop?  Ever smelled fresh bread baking?  Yes, those smells are the good ones.  If you smell garbage then it is time to eat elsewhere.  Tim DeCapua is a picky eater.
