From its central station in Groupon's bustling River North office, Hello, Food nourishes employees with internationally inspired meals crafted with organic and sustainable ingredients. Helmed by executive chef Mario E. Morales—whose culinary career has included stints at two Michelin-starred restaurants—the staff of kitchen experts begin their work at 7:30 a.m., when breakfast offerings ranging from syrupy towers of pancakes to heart-healthy egg-white breakfast sandwiches help office dwellers start the day. As the hours wear on, sandwiches piled with grilled salmon or roasted pork face off against alfredo pasta, stuffed burritos, or sizzling Asian stir-fries. Rotating menus feature six options per day, allowing visitors to add novelty to their meal routines without hiring a mime nutritionist, and an array of grab-and-go edibles keep latecomers sated when the café has stopped serving. The new taqueria offers low-priced food options as well. Some lunch station are open until 2:30 p.m., and soups are served until 4 p.m. Meanwhile, an onsite barista froths and infuses caffeinated beverages each day until 4 p.m. Hello, Food is accessible only to Groupon employees and their guests.
