Brian was the best tour guide! He knew SO much about the city. He is kind and polite, and the tour does not feel scripted. My husband and I were only in San Fransisco for 1.5 days and booked this tour to see the city in a quick way, and I'm so glad we did! You see pretty much all of the city and get to places the big buses cannot go. The bus is clean, he's a great driver, and he gives you local snacks! Would definitely recommend to anyone, even if you have been to San Francisco before! You learn so much!
