We had lunch here Tuesday 25 March 2014. I had the ultra burger - yes it was expensive - but wow! I never knew what a hamburger could be like. I've had good burgers before, but this far exceeded my expectations and took a burger to a level I didn't know it could achieve. The braised short rib meat below the black angus patty really set this apart giving a wonderful flavor of beef and very tender too. The whole wheat bun was fresh and complimented the beef. My wife had the chicken breast sandwich. We swapped halves. The mole sauce was hotter than she liked - but that is dependent on your tastes; the chicken was very moist and properly prepared. Staff was courteous and attentive. Our son liked the rotating view of Las Vegas and we enjoyed Top of the World restaurant. We liked seeing the sky jumpers coming off the deck above us. Yes, it was an expensive burger-yet we got the view and a burger that blew my socks of - very glad we had lunch here.

This is solely for the review of the boba. I only got the boba here because I've mistaken it for No 1 Boba which is across from here. There are 3 boba shops that serve boba in Chinatown plaza alone.

Its one of those things you get what you pay for. $2.50 for a medium drink is cheap, but I still feel ripped off. I couldn't get boba because they ran out. The coconut was just okay. Could have been worst. The main issue is close to half my drink has ice left. I know its only $2.50, but loading it up with chunks of ice just makes you feel you're getting ripped off.

You have Volcano Tea and Tea Station within a couple of yards away. There shouldn't be any reason to come here for boba.
