A food tour in New York is absolutely worth it. The city is so large, it's impossible to eat everywhere, especially if you're on vacation and have a limited number of meals in the city. A food tour is a great way to have some great food, learn some history, and find some new restaurants (new to you, not necessarily new to New York). My dad and I had an amazing time on our tour. And, we're both native New Yorkers. So, if you're visiting the area, and all you know you want to eat for sure is a slice of New York pizza and a dirty water dog, definitely take a tour so you can enjoy some great restaurants that might not have made your list if you just Googled places to eat.
