There are only two places to get a really good hot dog in the Valley and this is one of them. Prices are reasonable and the variety of hot dogs is very good. Try starting out with the basic "snap dog." I like them with just mustard , onion and relish.
One of my problems is I find something I like at a restaurant and whenever I go back I order the same thing. The menu at Pttsburgh Willys offers a lot of variety. I have to try some different hot dogs.
And, I will :)
