Ha! Good to know. I will check out Taboo next week, when my girlfriend is here too. I actually also went to Insomnia the other day, a café near Shi-Da.
There were some gay movie posters and one for a local lesbian magazine called LEZS. The two waitresses I talked to (and, by the looks of it, all the others too) were gay, so that was pretty cool! I asked about the magazine and they had a few for me to read. After a few hours of slowly ploughing through the magazines I now know words like 性別雷達 (gaydar) and 變裝皇后 (dragqueen)。Awesome! It's not a gay café per se, but definitively a welcoming environment.
They also recommended Taboo on Wednesdays for live music, might drop by then.
Hope to meet some of you next week!
