I had an entirely pleasant experience at Burgers 2 Beer, and I don't know why people seem to dislike it so much.
The burger I had, The Good, The Bad, and The Ugly, was tasty and everything I expected it to be. The fries were fresh cut and delicious, and even the salad I started with, Nature's Bounty, was good.
The beer list, at least compared to places like the Winking Lizard and B Spot, was somewhat lacking. But, they had Great Lakes Christmas Ale when I went, and I would have gotten that no matter how large a beer list was in front of me.
The service was good, too, so essentially I have nothing to complain about. It was a good dinner and I think 4-stars is more than warranted.
