With over 2000 reviews and a 4-star rating, my review will do little to impact the average. I'll still put in my two cents:
After finishing the meal, my thought was that those giving Burgr 4* don't get around much. Maybe they live in a city with lousy food and this really mediocre burger is "the best ever".
My first reaction to the menu was that I may come back. There are a lot of fun items on it in addition to the burgers. I ended up ordering the Farm Burger and the Aioli / Parmesan fries. This was on the strong recommendation of the server (and many reviews here). In the end: Ho-Hum cheese, ho-hum duck bacon, a fried egg that was over done ( the yolk should be runny and become like a sauce to the burger; it was fully cooked). Worse yet, my Medium-Rare burger came medium-well. I wanted to yell out "You Donkey! You overcooked the #@$%@ Burger". I dealt with it as unless something egregiously bad I don't like to send it back as I know it goes straight to the bin. The parmesan fries are large rectangular cut. The aioli was good, but that's hard to mess up. The fries were a bit chewy. Not crisp outside, soft inside as they should be. I get way better fries from fry trucks at home.
I don't get the four stars. Even if the meat was done right, it would not have been great.
