Typically Ranch dressing. Hooters has a pinkish tangier take on the sauce (which is prob my fave..I know, classy and all lol).
I've been to Hooters. The food wasn't bad at all. I thought someone might have said Ranch dressing. That just seems very odd to me. I've never combined that with pickles in any form (although I do use Ranch dressing for a variety of other fried foods).
A bit off topic, but for those that like to add just a bit of heat, I almost always add some Sriracha sauce to my Ranch dressing when I use it as a dipping sauce.
