We enjoyed the Little Italy tour with the owner of the company, Martin, who treats you like royalty from beginning to end. He knows a LOT about Boston history and picked many of the best places to visit. You really see the entire North End when you go on this tour, especially some out of the way places you wouldn't normally know about. Besides that, he has the pizza places all planned out and goes to get it for you so you don't have to wait in line (even at the most popular place in Boston, Pizzeria Regina, where the line was out the door). I got my ticket through LivingSocial, so it cost only $17--an unbeatable deal. Next time I have family visiting from out of town, I will definitely treat them to this experience.
The one thing you might want to bring is a beverage, since that is not included. We bought drinks at the pizza places we went to, but you can always stop in a convenience store along the tour.More
