Fortunately for me, I have the stomach to "test" local "eats" when on vacation. I know it's not for everyone, but I try to avoid any chain restaurants unless they offer something totally unique like some McDonalds do in other countries. My mentality is that I may never get to try this great BBQ, Pizza, Hot Dog, Philly Cheesesteak, gumbo, or ratatouille again for a long time so why not make my stomach know that it's on vacation too?
SFGA should not be thrilled. As you mentioned, the food was left to be desired! Funnel Cakes, while not a complete meal, are very tasty!
