We took the red line to go to Danshui. We strolled around Old Street and got various street snacks (潤餅, green onion pancake, chives dumplings). It felt intense walking through a traditional market - the majority of the vendors sell freshly-caught seafood, and there were a lot of people. Motorcycles also tried to squeeze through the already-narrow lane.
We walked along the golden coast and shared a grilled squid. On the way back we got some iron eggs and bought ginseng Oolong tea (loose leaves). It was a windy day, but nothing we aren't used to from SF.
