Or Costco for really cheap food, even if you're not a member (I am one, FWIW). They don't require a membership card to go in through the out-door (because this is how you reach the customer service desk to sign up for a membership), and at busy times walking in through there is completely painless. The food court is in that same (post-checkout) area near the out-door, and also doesn't check membership. Most of the food is a decent value, but in particular you can get a huge all-beef 1/4lb hotdog and a fountain drink for $1.50, or their "chicken bake" for $3. I don't know why more non-members don't take advantage of it. They'd probably change things if too many people did, because they can't be making any money on those two items in particular.
