Many people have a love it or hate it attitude when it comes to Quickly. I have quickly (lol) become addicted to their strawberry rose tea with tapioca. Boba teas (bubble tea) is really popular in SF in this is just one of the many places you can go to get it. Quickly is all around the city. There are many other boba places in Chinatown so don't feel limited to this one. Other great flavors are thai milk tea, ginger milk tea, taro milk tea. Quickly can be hit or miss but I love their greasy snacks like popcorn chicken and fried mini octopus.
Another fun thing to do is read the menu just b/c the spelling/grammar is terrible. Yes, I'm a nerd.
If you want to avoid this place, check out the Sweetheart Cafe on Grant Avenue
