It's the Wanhua district. There are old Chinese buildings and stores in the area. I like it.
If you walk northward from the Wanhua district and cross the Zhongdu street, you have modern and up-to-date buildings with hair salons, apparel shops, Japanese magazine stores, anime shops and many antenna shops for Taiwan's teenagers. It's Ximending, which has been Taipei's downtown area since the era when Japan ruled this island.
Ximending is now the area just like Akihabara in Japan.... Some people walking on the streets had a big tote bag which anime characters were vividly printed on it. Some people had cosplay. Even a "maid" stood on the street as you see in Akihabara. She was very cute. I hope I could've been fluent enough in Chinese to speak to her ;-)
I ate Luroufan for lunch at a food court of this district. It costed NT$40.
One more thing I would like to add. I’ve been reading assorted bloggers lately expressing their declining enthusiasm for anime, and complaining about this season’s lack of good shows. For me, zero could be further from the truth. For me, this season is 1 of the strongest of all time. I believe anime is becoming stronger than ever, and we are in the eye of a genuine golden age, despite the industry’s fiscal woes.
