520 Wu Er Ling is a small dessert cafe on Yaowarat Road in Bangkok's Chinatown, serving gelato and waffles. Waffles are baked to order in the shop and come with strawberry jam and whipped cream, and coconut ice cream is served in a fresh coconut. The air conditioning runs strong, making it a place to cool off and rest while walking Yaowarat. The shop is narrow, so seating more than three people is difficult.
