Shilin Night Market
Perhaps the most famous shopping area in the city, Shilin Night Market is a one-stop shop for tourists. From souvenir items, to clothes and shoes, to Taiwanese food and novelty eats - you want to check it out at least once.
Milk tea shops are ubiquitous, and massage parlors aren't spread far apart, so tourists who are tired of shopping have spots available to relax. The prices in most shops are not fixed so haggling is a skill that will be useful here.
