I'm no newbie when it comes to food tours, especially Secret Food Tours. We've done the one in Paris and will be doing them in Rome and Madrid very soon. I was so excited to hear that the company had made its way to the US.
I always recommend this company because there is no better way to learn about a city or a culture than through food, and Charlotte held no exception to this. We've been to San Francisco before but never to the mission district and she was able to give us so much information about the area and the art culture and delicious treats along the way. She even took photos for us every step of the way as we enjoyed tasty treats. One of the reasons I like this company is that in comparison to others, you won't leave hungry(although you might want to not listen to your stomach and go for me) and the wine is always an excellent touch. By the end I felt like we just had an amazing experience with an old friend, not just a good tour guide.
If you are looking to tour a piece of the city, step away from the Golden Gate Bridge and get some tasty food with excellent company you will certainly not be disappointed.
Side Note: the area is super accessible via public transit, through BART or Muni.
