Found an awesome Groupon deal for this place. $12 for $25 worth of food. Yay! It's located a few blocks from the strip, but very close to my hotel the Hard Rock.
Gets very busy during lunch time, you might have to sit at the bar if you can't wait. We ended up sitting at the bar because they told us it would be a 45min wait. The bartender/waitress was very nice and we had a good conversation with out about Vegas/touring etc.
This place is a lot like The Counter (in bay area CA). You make your own burgers. Different from the Counter, you can specify how you want the patty cooked. Overall, my burger was ok. It was very huge though and I had a hard time putting it in my mouth (that's what she said). Lots of mushrooms! The sweet potato fries are served with honey mustard and they're great.
They've got a great 2 for 1 deal through Yelp. Stop on by if you're hungry.
