Chicago Memorial Day marked the official start of grilling season. Not for you, though (you're terrible at cooking meat), but for... you know... other people. So instead, leave things to the professionals by checking out the latest steak additions to some of Chicago's best steakhouse menus. High Plains Bison Filet at Wildfire: You've probably had a bison burger before, but have you ever had a bison not-burger? If you haven't (or really, even if you have), you're gonna want to make Wildfire's new High Plains Bison Filet your first. It's a beautiful cut of coffee-rubbed Oregon Trail meat served on a small slice of toasted baguette, and topped with the perfectest perfect piece of butter.
