Here is my evidence that Big Belly Burger was originally not a fast food restaurant, but was a chain diner.
Arrow Ep 3 Lone Gunman- Tommy, Diggle, and Oliver go into the restaurant Tommy says the Waitress is hot. What fast food place has a waitress? If you have a waitress it isn't fast food.
Ep 4 An Innocent Man- Carly brings Diggle his food. Oliver sits down with Diggle and Oliver tells him about his mission. Another waitress walks by writing on a pad. Meaning she had just taken an order. What fast food place has waitresses taking orders? Later in the episode Carly and Diggle talk at the restaurant again and Diggle has a black mug. What fast food place has real mugs?
Ep 6 Legacies- Oliver and his Mom eat at Big Belly. They have milkshakes in glasses. Moira says it's a really good burger and says "I bet Carter Boeings doesn't know how to find the best burger joint in Starling City."
Ep 8 Vendetta- Carly asks Oliver and Helena if she can get them anything else, like a waitress would say! They are drinking coffee out of mugs.
Ep 11 Trust But Verify- Ben Browder and Diggle drink coffee (out of mugs again) and Carly gives Ben a piece of cake. Ben leaves, but leaves Carly a tip. What the hell fast food restaurant do you tip a waitress?
Ep 15 Dodger- Carly says she's sorry it took her so long (to bring them sugar) but she'd been waiting on rowdy customers (some kids). Diggle and Oliver are sipping coffee out of mugs again. And Felicity is there at Big Belly for the first time.
That's it. That's the last time they used the set.
