Help me find this restaurant - I can't remember the name

Vague description, I know. First, I believe it's right off the GSP between Stone Harbor and AC. There is a second location near Philadelphia, possibly in Cherry Hill. It's a roadside place, reminds me of a Stewart's, with a pretty big menu, huge pastries in the pastry case, and they sold jars of homemade hot mustard at the counter. Most memorable item from lunch was the homemade potato chips. There were no other buildings nearby. No more than 1/2 mile off the exit (which one? Not sure). We all think there was a cowboy or circus either in the name or on the sign. We are going that way in a couple of weeks and would like to get more of that mustard, and maybe a big ole breakfast this time. Anyone know where I'm talking about? I've been searching online for two hours with no luck :( thanks!!
