My brother and I joined one of the tours in March. Tammy knew a lot about the town, its growth, and it's food (and drink).
We were treated to diverse tastings of local fare, Portuguese food, Spanish tapas, wine, tea, and cupcakes/dessert. It was a well-curated experience.
I liked the small group size and that all the locations were in walking distance. Next time I return to town, I'd love to take the afternoon/evening tour.
