City Mart
This citywide chain of small supermarkets offers the best selection of edible souvenirs. Among the many options in the grocery section of the store are the makings for pickled tea-leaf salad (leaves and fried beans), which is served across the country, and all manner of candy ranging from ginger chews to chocolates. You’ll also find local teas, beers, and spirits. The Chinatown branch is particularly handy.
