Happy Hour is a marketing term for a period of time in which a restaurant or bar offers discounts on alcoholic drinks, such as beer, wine, and cocktails.

Typically, it is in the late afternoon everyday in HK, usually taking place at some period between 4 PM and 9 PM. This promotion is intended to boost business on what may otherwise be a slow day. In most cases the "happy hour" lasts longer than a single hour.
