We've done food tours in many different cities. Some are great. Some are not.....so far, Seattle was our favorite, but a lot depends on the guide.
I would think NYC has some good ones, but in reading Yelp yesterday, I wasn't impressed. Sounded like they'd give you a small taste then expect you to purchase the rest.
We are thinking go to a matinee then out to eat, but I do want something authentic, and still not sure where to go.
I'm thinking a great Italian place that is all homemade would be best.
Just my opinion, of course.
