Quiznos
Quiznos is comparable to Subway in that they both offer sub sandwich menu options like the Tuna Melt, Classic Italian sub, and Meatball sub. Quiznos also offers the popular Spicy Monterey and Turkey Ranch & Swiss sandwiches. But the franchise has a major Achilles heel, and some customers might have already noticed the reason why you typically see more Subway restaurants in crowded cities than Quiznos locations.
