Burgatory....you had me at boozy milkshakes.
Overall, I dig this place, and my fiance loves it! I'm not as crazy about burgers, but I usually do the ground chicken and I really enjoy it. You can create your own, which I'm always a fan of and they have some decent options that you don't see everywhere like truffled shallot aioli and gruyere cheese.
Although this place is known for it's burgers, I'm actually a bigger fan of the nachos (get them, you'll thank me later) and the shakes.
The downsides? It's generally a huge wait, it's often loud, and if you end up seated in the tent area in one of the high top tables, you have no where to put your belongings (read: purse).
Overall, it's a great spot for a delicious burger and shake.
