JT’s Genuine is a sandwich shop in Irving Park with a menu of about 13 sandwiches that are so meticulously constructed it seems like they were engineered by NASA. There’s a breaded pork tenderloin that’s beautifully tender, and thinly pounded so that the meat is sticking out of the buttery bun like one of Saturn’s rings. The “roast turkey” is actually a Thanksgiving sandwich, a perfect balance of cranberry sauce, stuffing, and mayo on thick, toasted white bread. The counter-service space is small, but there are a few tables if you want to eat there. And if you get your sandwiches to go, everything is carefully wrapped and travels very well.
