茶餐廳 Cha Chaan Tengs, translated directly as ‘tea restaurants’, are Hong Kong-style cafés that are an essential part of the city’s culture. Cha Chaan Tengs sprang up in the 1950s as an affordable alternative to high class western restaurants.

三點三 (15:15), meaning 3:15 in the afternoon, is a Cantonese slang for "Teatime at Cha Chaan Teng."
