Visiting SF for three nights, recommendations needed

Hi 👋 Me and my friend are visiting SF from Idaho through highway 101 and getting there Sunday afternoon. My friend has a flight to catch at 4 on Tuesday. I am going back to Idaho through Nevada Wednesday morning.

We are planning to do a bike ride around the city and other free things we can do. We're staying in a hotel near Chinatown. Any food, place, or any recommendations would be very helpful. Thanks in advance. We like sushi, Spanish, Azerbaijani, and Asian food. Anything close to them is okay too 😊

We are 19 and 20 year olds. I am gay, I want to try something unique in SF maybe on Tuesday night when I am by myself.
