Tea houses and snack bars refer to Taiwan's early specialized industries. These establishments typically feature karaoke machines and offer snacks that pair well with drinks, allowing guests to enjoy singing and drinking with the service staff. The experiences can range from simple hand-holding to varying levels of special services. Because the clientele mainly consists of middle-aged to older men, these establishments are affectionately nicknamed "grandpa shops" — a concept that inspired the creation of Pure Love Snack Bar. This somewhat exclusive venue lights up the tipsy nights of men and women in the alleys of the Gongguan commercial district.
