While I'm on a franchise-binge lately, I suppose I'll review my go-to Harvey's.
In terms of fast food, I think Harvey's serves one of the best burgers out there. I don't think I've ever been served one that wasn't totally plump and juicy, and they're definitely generous with the toppings. I'm also a pretty big fan of their onion rings. Deliciousness all around.
The staff is also very friendly, and there are plenty of tables to accomodate crowds.
