Grandma's sour plum soup, every time I used to stroll through Tamsui Old Street, I had to buy a cup (I don't even know why, hahaha). It's not particularly special, but it has a familiar yet strange taste, like sipping on a memory. The environment and setup are pretty much the same as I remember, just the people might be different. Whenever I come back, I will still buy a cup to drink.
