We arrived in Barcelona before our Rick Steves My Way Spain tour (terrific, by the way - shout out to Jesus, our tour manager!). Before joining the tour we thought a short food tour would be fun, and we were not disappointed.
This is the one we did: https://www.tripadvisor.com/AttractionProductReview-g187497-d11763957-Barcelona_Private_Food_Tour_With_Locals_6_or_10_Tastings-Barcelona_Catalonia.html Our guide Adi was excellent. It is our first trip to Spain so this intro to the cuisine (6 tastings) was very helpful. We learned about many common tapas and churros from Adi and he led us to the best versions of each, starting with selections from the Boqueria. Great guide and fun experience! Highly recommend. So if you’re on the fence I urge you to try it.
