My wife and I took this tour on a beautiful fall day. It's a walking tour through Little Italy and the adjacent Chinatown. The first few stops are Italian delis where you try a cannoli, prosciutto & mozzarella, gnocchi, and cheese & olives. In Chinatown, you stop for tea & dim sum, dumplings, and pastry.
The food was all excellent and we left pleasantly full (but not stuffed). There are plenty of good stories about how food shaped the Italian culture, how the Chinese adapted their own food to integrate into the culture, and the history of landmarks like Columbus Park and the Bloody Angle. It's a fun, thorough tour that is well worth the time and money.
