San Francisco travel tips
1) Start your San Francisco exploration from Union Square | In the area with the same name, there is one of the central squares of San Francisco – Union Square. This square serves as a meeting point for local residents and becomes the beginning of an acquaintance with the city for tourists. From all sides, the square is surrounded by shopping centres, hotels, restaurants, souvenir shops, and galleries. The square welcomes its guests around the clock, without stopping for a minute. |

2) There are two airports near San Francisco, so look carefully at the name on the ticket | The closest airports to the city are San Francisco International Airport (SFО) and Oakland International Airport (OAK). From both airports, the city centre can be quickly reached by the BART train, an intercity transport line in the Bay Area. |
3) Combine dinner and movie watching in an atmospheric venue in San Francisco | You can combine dinner and watching a movie in the vintage cinema Alamo Draft House with a bar and kitchen. It often hosts weeks of festival films or evenings of little-known insane art-house movies from the past. |
