Start your day with a caffeine boost and quick breakfast at Yonghe Soy Milk King (永和豆漿) near Guting MRT, then hop on the MRT to Zhongxiao Dunhua. Begin the TCG crawl at Gashapon & Card Station and then walk to the nearby Card Monster (卡片怪獸) to browse sealed boxes, loose singles and demo some Standard decks; the staff often have local trade lists and can point you to upcoming events. Finish the morning with a mid-morning snack — grab a pineapple bun and milk tea at a nearby bakery before heading to the next shop.
After lunch at a Taiwanese bento shop or beef noodle spot around Zhongxiao, take the MRT to Ximending and explore the gaming-focused stores like Toys'R'Us Ximending pop-up sections and the specialty card shop 'TCG Master' tucked down an alley, where you can open booster packs and compare rarities with friendly collectors. Continue to the Beitou/Shipai area by MRT and a short bus/taxi to visit Game Square Taipei for vintage pulls and tournament flyers; use this time to trade, ask about local league nights, and pick up a fresh deck sleeve or playmat.
Conclude the day back in central Taipei with dinner at Ningxia Night Market, sampling garlic shrimp, oyster omelet and bubble tea while hunting for cute Pokémon-themed snacks or small souvenirs from market stalls. If you still have energy, drop into a late-night café or hobby bar near Taipei Main Station where locals meet for casual battles and deck-building sessions — a perfect low-key way to test purchases and swap contact info for future meetups.
