Dongmen is a very popular yet chill shopping/tourist spot in Taipei. There is a corner that sells spring onion pancakes on high demand all the time, and with a good reason. I had the basil-egg spring onion pancake and it was very tasty. Freshly made on spot and the basil gave it a nice aroma. Definitely a good snack for a break in between shopping.
