Since no location was specified, here are a couple of the best burger places I've found outside of Toronto...
Absolute best: Port 'O Call in New Orleans. They take an entire sirloin steak, put it through the grinder and fry it up.
Also excellent: Ted Peter's in St. Petersburg, FL
While it's no longer around, there used to be a place in Montreal called Piazza Tomasso that served one of the most delicious burgers ever. It wasn't on the menu but could be special ordered. Didn't even taste like ground beef but was quite sweet. Someone once told me that they used horsemeat. Whatever... it tasted great.
