Food tours like these are the perfect thing to do if you're only going to be in a certain town for a couple days and would like to get as much of a taste of the local flavor as you can. At $40 a person, it's a bit more expensive than a single meal would be, but you get such a wide variety, it's like you're eating a half dozen meals at once. This company offers tours of Pike's Place Market and Belltown.
I went on this great food tour a few years ago, and must say that I found it extremely good value for money. The food samples were brilliant, and the lady running it was a great person to chat to and had this easy way of making you feel part of the family as she showed you around the query history and fab places to eat in Pike's Place Market and Belltown. Highly recommended.
