I have definitely found my favorite burger joint- TWISTED ROOT BURGER.
Awhile back I went with a group from work to the one over in Richardson, and had some hesitation because I'm trying to lose my "baby weight", but I wanted to socialize after returning to work from maternity leave.
What a pleasant surprise when I ordered a turkey burger, and found it to be BETTER than a regular burger. The atmosphere was fun, they call your order according to the "celebrity name" they assign you, and it's lively and fresh.
I highly recommend it and look forward to going back!
