I've read all the way to the bottom of this page seeking hot dog tips, but finding few. In Chicago in August for a business trip and I'd like to have a couple of really good hot dogs. I"ll be at the Sheraton on E. North Water St., but don't mind walking or cabbing for a REALLY good one. Any suggestions? And also, though I've decided to eat almost every night on Devon Ave., I would love a really good sushi dinner, if anyone would care to venture an opinion on that.
