Apologies. I have read the boards and am overwhelmed. My 15 year-old son and I will have 5 nights in each of Florence (Hotel Gallery Art), Rome (Hotel Minerva), and Venice (Bauer Hotel) in late June/early July. This will be our second (or more) vist to each city. Past travels were in August with many closed restaurants. My son will be delighted with pasta every night. I will want memorable, yummy, and fun spots. Think Trattoria Garga! Many thanks for your suggestions.
P.S. We need an extra lively place on June 30 in Rome where we will host my older son and his 4 school mates for my son's 18th birthday!!
