The cooks at Firehouse Burger grill up scrumptious beef patties enlivened by free toppings and paired with a panoply of creamy milkshakes. Duos and quartets each select any one-patty burger from the eatery’s menu, which includes options such as the Ladder 41 bacon cheeseburger slathered in barbecue sauce and loaded with onion rings. After picking a base, patrons pile on opulent free toppings such as lettuce, tomato, and freshly minted 20-dollar bills. Hose down hearty bites of burger and crisp french fries with a 21-ounce fountain drink or an 8-ounce cherry, apple, or lemon milkshake. Diners can relax in the venue’s outdoor seating area and listen as the wind whispers winning lottery numbers into attentive ears, or they can admire the full-size fire truck that stands sentinel-like outside the eatery, lending it its name.
