At the Original Tommy's World Famous Hamburgers, the ingredients are of the highest quality, including 100% beef patties and hot dogs, double-thick slices of real cheese, fresh chopped onions, hand-sliced beefsteak tomatoes, pickles, and mustard. All items are prepared to order, and extra portions of chili, mustard, onion, or tomato are offered at no extra charge; portions are extremely generous. As food costs are much higher than industry standards, the restaurants are profitable due only to the high volume of customer traffic.
