Two popular fast food restaurants are on the way to Rockville Pike, opening this fall outside Wintergreen Plaza in the space once occupied by Ted’s 355 Diner. The Habit Burger Grill, a fast-growing chain from California that’s making its Maryland debut, offers a Shake Shackish menu of burgers, fries, onion rings and ice cream-based drinks. Jersey Mike’s Subs, with nearly 200 locations nationwide, has a extensive selection of subs and wraps plus gluten-free and carb-free options.
