Whether you call it a hoagie or a po' boy, a grinder or a torpedo, a hero or just a plain old sub, Quizno's makes these kinds of food items.
Quiznos makes hot submarine sandwiches. I'm sure they make other things too but I can't be bothered enough to actually research their menu. I'd venture a guess and say it's quite likely they make some things with like...lettuce in them. Lettuce is pretty common. Spices? Maybe they use some spices as well.
Quiznos has really high stools so when you lean over to start vomiting out your meal everyone in the lower uncomfortable booths can get a good look at you.
Real submarines are full of seamen almost 100% of the time
Quizno's submarine sandwiches, about 6%
On a real submarine one may experience feelings of claustrophobia
At Quizno's, you'll probably just get the shits
