I rarely go on food tours because I prefer to wander around on my own. But the tour I took in Malta was an example of why one should take a food tour.
In Valletta, I joined a tour with the Valletta Street Food and Culture Walking Tour, found by my friend on TripAdvisor. This tour was great. Not just food, but culture, history, and movie locations.
It was good value for money, the walking was not too strenuous, and guide was great (guides must be licensed in Malta so they have to know their stuff).
The cost is about $43 per person and for that you get four food and culture stops and three hours of information about Malta.
The guide will ask you to pre-select if you want to try the horse meat.
The amounts of food are not overly huge but enough that you will not need to eat lunch.
At the final stop, you get free beer, an appetizer slate, and a small main dish.
Conveniently, the tour ends in a food hall so you can keep eating if you are still hungry or just want to sit for a while.
