Pat's Kountry Kitchen
I've not been to Pat's in Old Saybrook in several years, but the menu used to state that there could be no substitutions. That was brought to my attention by our server when I ordered the clam hash and asked for it with two eggs. She said that was impossible because it came with just one egg and no substitutions were allowed. For emphasis she pointed to the no substitutions line on the menu. I haven't been back since.
