We needed a convenient, relatively cheap place to eat and this was right in the Cosmopolitan Hotel (across from Marquee). There is no way this place could go out of business in this location. They serve gourmet burgers and spiked milkshakes. Is there anything you can't get drunk on in Vegas? The burgers are pretty damn good, but it was really only a better version of Red Robin, with an upgraded (better looking) wait staff. The essential complement to burgers - the fries - were a disappointment. They seemed overcooked.
Service was extremely slow, even though there were plenty of empty tables, but our waitress kept us updated. I had nearly finished my shake by then.
3 stars for now. This place has potential, but I doubt anyone cares all that much as you can't miss with burgers, fries, and shakes.
