This was an excellent find, we went here with around 8 people and had to wait for about an hour or so for a table to open up - but it was TOTALLY worth the wait. Once we got seated, we had to go over the menu for about 15 minutes before we could figure out what to order. I'd highly recommend checking out their menu BEFORE you're seated, you'll want to build your own burger and they have a TON of options - it's like the Cheesecake Factory menu in size but only contains burger options and condiments. They have a nice selection of drinks as well.
It's kinda cool that it's owned by Hubert Keller that you see on Top Chef and Top Chef Masters from time to time...
Honestly, this was the best meal that we ate on this trip. I'd highly recommend the Burger Bar!
