I prefer my burgers Med-Rare, so that cuts out many joints from having a decent, edible burger. Damn Food Police. My favorite joint? Mine.
Nothing like a half pounder, done right on the grill with anything from a Sesame Kaiser, to some great ciabatta for a roll, good cheese, anything from Blue to co-jack, thick cut bacon, or one of a hundred different toppings. The drinks are always cold, the company is great, and you can go directly to the cigar lounge after dining, if it strikes the fancy.
