LOVE this place. The promotional materials say that BurGR "takes the traditional burger, fries and milkshake comfort food combination to an entirely new level," and that's not hyperbole. We had the Uber Cheese Burger (3 kinds of cheese, fantastic gooey goodness), the Chicken Sliders (good sized, a little aggressively spiced) and the truffle fries (huge portion, more than enough for two to split). Nothing disappointed, and it was enough food that we didn't finish the fries, despite our best efforts.
Our servers were both terrific: Gianna, who my date described as "put-her-in-a-teacup-cute," and Alex, who knows his way around a beer list. (On that note, the beer list here is not world-beating, but is passably broad and reasonably priced.) The servers and host staff are decked out in form-fitting '60s-flight-attendant-inspired uniforms, which is a nice touch and good eye candy.
Easily a level above Holstein's at the Cosmo. I'll definitely be back.
