This place is obviously a big tourist attraction, and it works. The blue burger and "just" fries I got were nothing short of excellent! Service was good, too. We got lucky and did not have to wait in line to get inside, since we went on a Wednesday night.
One nice touch that was unique was that when you get the bill at the end, there is an iPhone inside asking you to complete a survey based on your experience. Somebody must have money if he can put an iPhone inside every bill holder!
The only thing I don't like about this place is that it is too loud inside. It's one of those restaurants where the music is played so loud that it's hard to hear your server or even have a conversation for that matter. However, I let them know about that in the survey, so at least they seem to care about customer feedback.
I would gladly come back to try another burger. Gordon Ramsay did well here.
