Planning next day's trip at restaurant L'Angoletto ai Musei.

This really was an excellent address near the Vatican, courtesy of Le Guide du Routard, the French equivalent of the Lonely Planet guide.
A purely Italian trattoria where the only language spoken apart from Italian was the language of the signs.
The only thing was, every time the door opened with the memorable bell ring -and it did four times within 10 minutes- you could bet the customers knew some French. That's what we can expect from such guides I guess.
