My sister and her husband were passing through the Miami airport on their way to Costa Rica. They landed just before 6:00 am and had a 5 hour layover which was plenty of time to pick them up and take them for breakfast. We hadn't seen my sister and brother-in-law since our trip to California last year so it was wonderful to see them even if it was only for a couple of hours!!
Although there wasn't much open that early we headed down to South Beach and went to our favorite South American Bakery, The Charlotte Bakery. They have the most delicious empanadas and pastries. If you are ever in the area you should really check them out.
