I finally got to try Barrel Burgers. Nestled aside Whole Foods Market in Huntersville, this place offers freshly grilled made to order burgers with fresh "healthier" toppings (i.e. mixed greens vs. iceberg lettuce).
You walk up to the bar to place your order and then wait 10-15 minutes as it is prepared. Customer service was lacking, as the Grillmaster keyed the order into the computer and slapped the burger on the grill. There is no table service, and seating is somewhat limited. Although there is additional seating outdoors, or over in the Whole Foods Market area.
They offer a few brews on tap, but no other beverages are available unless purchased over in the market separately. The burger was decent. I wouldn't call it the best burger that I've ever had, but it certainly wasn't horrible either. There just wasn't much wow factor. The fries were rather plain with some overly charcoaled tips. Both the burger and the fries could've used some seasoning.
As a close option to my office, I definitely think this could become a part of my lunch rotation, but I'm in no hurry to tell a friend.
