Though the atmosphere isn't the best, and the wait can be long, the burger absolutely makes up for all of that...and more. I have never had a hamburger that good! What makes it taste the best, in my opinioin, are the grilled mushrooms. If you haven't tried it, do yourself a favor and go! It is a little pricey for a hamburger joint, but well worth it.
Pros: condiments galore, large portions, the best taste ever
Cons: long waits, cheap decorations, fairly pricey
