Looking for a fancy burger and shake place, with a mid-range price? This place is great, if you happen to be near the cosmopolitan. The regular or 'spiked' shakes are great, definitively filling. They fill your cup and you have half the shake mixing cup full with more. If you must try and have a small stomach-share one! Especially when you want to enjoy your burger. Al the burgers are good, depending what you have the taste for. For any pallet there is a burger for you.
Atmosphere is nice, chill and casual. No need for "club" attire, so perfect for something while out on or after sightseeing.
If you want to so more than just drink a shake or have a beer and actually want to eat, don't sit in the lounge area. The (coffee) tables are too low to properly eat a burger. If you don't want to eat stuff off your lap, then you should get a seat at the bar or the dining area. Otherwise there is nothing bad about this place.
