What's the best chain restaurant for a story?

I think Outback Steakhouse is the only chain with a Blooming Onion at the moment.

 

Actually, that's even better. This way my character is craving the blooming onion, but she doesn't get it because she's at the wrong chain. Things aren't going her way. And now the zombies are probably going to get her. Thanks.

 

It just seems like a very popular item amongst chain restaurant eaters. Both myself and my characters are very unhappy that they're at the wrong restaurant for that.

 

Story is done!!! But I'm sure it won't be my last story set in a chain restaurant.
