Check out the "Regional Passes" for
Italy
Get your self a pass for 7 days of travel in "X" amount of months. This works by allowing you to travel for so many days ina a given amount of time (months). In one day ( I dont htink they use a 24 hour day... I think its like 20 hours) you can travel as many times as you like and it only counts as one day. Its not by the trip. Bsically, my wife and I did Venice to Florence in the AM, arrived in florence, then checkinto new hotel, got on train and went to another city to look around... all basically one trip. ALWAYS KEEP YOUR LUGGAGE CLOSE!!! and in sight!
As far as food goes... do you speak Italian? or anyone with you? Fortionately its my wifes first language, and its helped alot... was a life saver when I almost got arrested in florence. anyway, try and find the "local" places.
In Florence find "The Yellow Bar" that was by far the best food on the entire trip. (steak)
In Venice.. (hopefully the water will be low), the food along the canal is expensive and usually smaller portions. You gotta try the Gellato (sp?) their ice cream... Fruito de bosco (sp?) (fruit of the woods... mmmm good stuff).
Rome, Rome had a ton of good places... Most were off the beaten trail. Fresh buffalo mozz and prosuitto (sp?).... ohhh!
Don't expect large portions anywhere. Breakfast is usually breads jams and maybe some fruit. Some of the hotels have eggs... but only a few.
I will get some more info for ya... when Iget home tonight.
