Great burger joint inside the Cosmo! Nice decor and atmosphere. Our table was wobbly, so being a designer in for the Hospitality Expo, I was a little po'd at this since everything else in this hotel is exquisitely designed. But, won't knock off points for that.\n\nThe food: ordered the \""Nom nom\"" burger...Kobe beef burger with cheese. It didn't come with lettuce, tomatoes, etc., but they're available for the asking. Overall, very good...not as melt-in-your-mouth as the kobe burger at one of Wolfgang Puck's restuarants, but tasty none the less. Got it with steak fries...again, good, but about the same as what you could get at say Fuddruckers or KFC; nothing special, but still good.\n\nService: Good. We could tell our server was either tired or just tired of working in Vegas, but at least she still made an effort to smile. Another server who accidentally poured water into my 1/2 empty Sprite glass was better and more fun. We all laughed, she realized her \""super fail\"" (as she exclaimed), apologized and provided me with extra soda and popcorn...which had me thinking, \""why didn't our main server give us popcorn when we first sat down??\""  Again, neither here nor there.\n\nFor the guys(& maybe some of you ladies): the servers in the bar area...wow. Very hot asian ladies in tight red mini-dresses?! Take that, Hooters!\n\nOverall, a nice casual place to eat amongst the swankier places in the Cosmopolitan. Definitely better than some of the other burger offerings in Vegas. Guys, if your girl doesn't wanna leave \""The Chandelier\"" bar, just go up and have a burger & watch the game at Holsteins! You're welcome.
