My cousins came to visit me in Paris this past summer. It was there very first trip out of the country. I had them buy the Rick Steves Paris and the museum apps for the smart phones. One of my favorite cafe's is in his guidebooks. So I took them their for lunch! L'Bouillante. We were enjoying our meal when up the stairs comes a TV crew followed by Rick Steves. We were surprised. He was so nice and came to our table and asked about our trip  - how the apps were working out etc. That's a real celebrity sighting!
