A large group of us dined here before the Britney show. It's definitely a good burger spot. We shared a bunch of starters which were all delicious - soba noodle salad, green salad, buffalo chx wings, along with their variety of fries. We were all stuffed by the time our burgers arrived. I ordered one with goat cheese, roasted tomato and truffle aioli. The truffle was not overpowering and just enough.
They have a ton of surrounding TVs and a good option if you're at planet hollywood. Although I wouldn't make it a destination.
