I guess part of it is, like I said, we're from the UK. When we come on vacation its usually for 2-3 weeks so part of the time is in Florida.
I guess you'll probably find it hard to believe but restaurants like Outback, Longhorn, etc are something that we don't get in the UK (in terms of quality and quantity of food) so we're more than happy to go to these places when we're off the boat. I guess with you guys based in the US you don't want to go to chain restaurant that you can go to every day of the week anyway.
Never used to have subway in the uk (theres tons of them now) we ALWAYS went to subway in FL. Of course, now we don't. We've had McD, Burger King, KFC for years in the UK so we don't go there - but we do go Wendys, SteaknShake etc.
Now you're going to think I'm really sad. We have ONE Dennys in Wales - its about an hours drive away from us. Yeh we go there sometimes.
