How safe is The Great Star Theater in Chinatown at night? (6-10pm)
Chinatown at night is generally pretty safe because there are a lot of restaurants with a lot of activity. It gets a little sketchy later in the evening, especially on weeknights, when you go down the hill, east of there, into the Financial District. There just isn't much activity down there at night.
This theater is quite near Columbus and Broadway, which the heart of the North Beach, so is wedged between Chinatown and North Beach. This area of town has heavy foot traffic until 2am when bars close, so personal risk is low. If you are driving in and trying to park, this is another matter. I think the St Mary's Square parking garage is closest. You can also park at Stockton garage, walk through Grant & Bush Chintown gate, then several blocks along Main Street of Chinatown to theater. I tried to find my tip for Stockton garage, but mobile version of VT freezes when I try to search my own pages, and a search on SF VT only turns up Stockton Hotel.
I heard it was closed except to special events. If you were attending a special event I'd say that it would be safe as can be.
The Great Star Theater has recently changed management. There are a still a number of events and shows that are held there and a link to the coming month or so performances is attached.
If you get a chance the theater itself is definitely unique and worth a visit. It was originally built in 1925 and is quite ornate inside.
Personally I have never had a problem visiting Chinatown at night or during the day. Use the same caution you do traveling and you should be fine.
