best burger. i've eaten a lot of burgers in my life at a lot of different burger joints all throughout michigan and various parts of the country. the blue apple burger (bleu cheese, applewood bacon) is the best burger i've every put in my mouth, ever. from the bun, to the toppings, to the expertly seasoned and prepared patty, the entire thing melts together in a perfect balance where you can make out the individual flavors, but the combination is distinct, unique, and terrific. very nicely done. oh, you mean to say i haven't mentioned the fries yet? not sure how that's possible. the fries are also out-of-this-world. i've sampled fries on the same spectrum as burgers and these are some of the best i've ever had as well -- crispy outside, perfectly seasoned, tender and flavorful on the inside with a distinct potato flavor -- the only fries i can think of that are in the ballpark here are in-n-out, crack fries at hopcat in gr, or the fries at stella's in gr; but, that's a short, and very distinguished list.
as an early entrant into the re-burgeoning corktown neighborhood, mercury is bound to become a neighborhood staple (to the extent it's not already) and get increasingly crowded. if you're in the mood for a burger, fries, and beer (with a beer list dominated by michigan craft beef), do yourself a favor and go now before it becomes absolutely impossible to get a seat.
