I usually prefer the stew.

I usually try for Subway, but they just raised their price on the meatball sub

Since I like to eat for cheap I have bought a couple $5 footlong's, but the options are miserable. Pretty sad when you're only two options are veggie subs or subs with ####ty processed meat.
The sweet onion chicken teriyaki sub is probably the best, but when fast food is running up to $10 you're paying too much.
Here are a couple local (Edmonton favorites):
Roadrunner Pizza: The service is awful (they probably spit on my food), but you get a lot for little money. A large pizza loaded with cheese for $8 is a steal in my book.
Fulton Market Burger: This one is out in Sherwood Park. It's sort of like Fat Burger, but 1000 times better. The food all around is good, and it's cheaper than FB as well.
There is a Jamaican/Jerk Chicken place in Millwoods (by the Rec Center) that is completely amazing. You get a ton of food for the price you pay. The poutines, burgers, and donairs are all perfectly made.
