It is indeed cool to see a stand alone boutique. This one is from Bovet. The boutique is located in Tienmou in Taipei City.
The boutique. The Chinese characters above the entrance is the Chinese name for the company (which has a long history in China). It is Bo Wei (pinyin). It is a bit different from the one you see on the Bovet website (in About Bovet, History tab) which is written and read right to left.
