Forget substitutions: When you want a burger done right, you custom order it. At least that’s what drives the popularity of Butcher & the Burger. Here, diners stare upward with gaped mouths trying to decide among ten patties listed on a giant chalkboard, ranging from grass-fed beef and elk to sustainably farmed salmon and free-range turkey—hand-mixed with a choice of 11 housemade seasonings. That’s even before getting to the buns (split-top egg butter, pretzel, croissant) and specialty toppings (griddled onion, wasabi mayo, pickle chips). Then, it’s choosing between chicory coffee and Café Bustelo espresso. Then, cinnamon-and-sugar or powdered-sugar beignets. These are tough decisions, people. But even with a little hemming and hawing at the counter, traffic flows smoothly through the 30-seat, counter-service BYOB. 1021 W Armitage Ave (773-697-3735).
