Only thing closer than Harry's is the lobby of your hotel. Some consider Harry's a "tourist trap" but I have been going to Harry's for decades and have always found the food and service to be excellent. Yes, it is expensive, but the maitre'd and waiters are very gracious about splitting orders and sharing orders. Moreover, there is a fixed price menu each day which is fairly priced. It is not a typical, local osteria or trattoria; it is legendary. However, having said that, it is really a lot of fun to go, hang out (ask for reservation downstairs) and see a bit of Venetian glamour. I suggest popping in the day before, talking to the maitre'd, tell him number of your party and ask for a nice table downstairs. If you are interested in white truffles, ask if any will be available on the 16th.
