I’ll try to post more about the places I visited later, but before I forget:
IF YOU WANT TO FIND PURIKURA IN TAIPEI! Take the MRT to Ximen Station, then find the Eslite store and go to level B1. (I feel like I’m giving instructions for a videogame cheat or something.) It really bugged me because I was trying to look up purikura places online and also asking Taiwanese friends if they knew anywhere to do purikura, but no one knew. BUT I STILL FOUND IT, HAHAHAHAHAHA!!!!! So FYI.
