We also love Waffle House. One of the things we look forward to driving to and from Florida is that we get to eat there a couple of times.
One word of caution, though. Outside of Florida (that has a smoking ban), Waffle House tends to be rather smokey. It is a small place, just one room, so they can't have a non-smoking section. Thankfully, smoking isn't permitted in restaurants in Florida so we can enjoy our meals there.
