The BurGR is a beautifully set out restaurant and full of lots of sharp-looking waitstaff, and despite a lengthy line for group-dining, as a single I was able to sit right down at the bar.  I ordered one of the special burger offereings, the uber cheeseburger medium well.  I think of burger-medium well as \""no pink in the middle,\"" or passably the tiniest bit of pink in the middle as ground beef should be cooked much more thoroughly than, say, a beef steak.  Many restaurants will not even have a medium-rare burger as an option owing to the chance of food poisoning from undercooked hamburgers.  When the burger arrived 25 minutes later, it looked gorgeous on its puffy roll, with the cheese nicely melted and the beef sporting a glazed, glistening look.  But the first bite into the burger crushed my enthusiasm.  If the burger was 1/2 inch thick, then the middle 1/4 inch all the way through the burger was pink.  2 days later I am comfortable stating that the burger did not make me sick, but for a guy's whose reputation is built on quality control, how he let this burger come out of his kitchen so underdone is a mystery.  I'll be curious to see what other reports come out of this restaurant.
