I had the Phoenix Times Best of Phoenix Pittsburgher at Wimpy's Paradise in Downtown Chandler. It was decent but, but I don't think it qualifies as the best in Phoenix. The bun was typical, the dog itself was sizable and of good quality, and it was topped with cut up ham and shredded cheese... but not overloaded by any means. All in all, nothing special... maybe even a little dry. For $7, I would pass on it.
I would like to try the burgers, and, if I did order another dog, it would need some chili or something. The folks working there seemed pretty nice.
