At the Mill St. Brewery on Saturday, I tried ordering a hamburger medium rare only to be told by the waiter that they can only cook it medium well or more due to the "burger law". I know this has been discussed before, but rather than argue with him, I thought I'd arm myself with clear cut facts first rather than spread misinformation.
Is it a law, an enforceable guideline or a recommendation that burgers have be cooked medium well and can't have any pink in them? If you have any official sources, please cite them as they would be excellent references to use when trying to order a hamburger your way.
I'd do a search, but I'm terrible at searching.
