The clinic I know of is located near the Dingxi MRT stop in Jhonghe. 地址：台北縣永和市福和路278號 電話：(02) 2922-6301 drko.com.tw/ This clinic will do them same day, but I think you have to be there before lunch. I don't think they do them in the evening, but I'm not sure, so you could call and check. You do not need an appointment. The cost is about NT$7,000 I believe, insurance cannot not be used on it anyway, so there's no issue with not having any. I think a passport must be shown though. Dr. Liu is my regular doctor there, and she speaks English, so communication should be fine. Let me know if you need any other info.
