If you go to the Philippines, you will find Shakey's all over the place. Many foreigners think it's a Filipino chain, but it's origins are from the US. I look forward to visiting this restaurant when in the Philippines as the Pizza is the closest to American made. Even better than Pizza Hut and Dominos there.

A couple from my youth that are not around in South Florida:

New England Oyster House. Good fresh Sea Food- Lobster, Crab, Raw Bar, great soups at very inexpensive prices. I don't remember if it was a chain, but every time we went to the location in Hollywood, FL it was packed and we would have 45 minute waits for a table.

Taco Viva-Fast food TexMex before Taco Bell became what it is. It was a South Florida institution. http://www.tacoviva.com/

One place that had many franchise locations in South Florida that are now closed, but the original "hole in the wall" location still exists in Dania Beach, FL. Tark's of Dania, which celebrated it's 50th Birthday last year.
