I was wrong.
The Rare T-Bone burger with deep fried onions, cheddar cheese, and truffle butter was the second best thing I'd ever eaten in a restaurant. I knocked that burger back like a sorority girl on pledge night. Then I found out why. Not only is the ground T-bone steak charbroiled, it's also flambed in Tequila. I have no idea if that significantly changed the flavor or texture of the burger, but it sure enhanced the coolness factor of what I had already eaten--which after three margaritas, is as important as the taste itself!
