"There are too many good things to say about the burger I had. It was hot, perfectly cooked, ingredients were all high quality, it was well packaged and traveled well in the to-go container, and tasted amazing. I’m so mad that I’ve walked by this place dozens of times and only just now tried it. I will definitely be going back and bringing friends."
