Starbucks Korea will host an Evening Event offering discounts of up to 50% on decaffeinated and caffeine-free beverages after 5 p.m. each day through May 18.

The promotion covers 20 menu items, including 11 types of decaffeinated coffee and 9 types of caffeine-free drinks.

Customers can receive a 30% discount on eligible beverages when ordering in-store, via Siren Order, or through delivery.

An additional discount applies if a beverage is purchased with a cake, raising the discount to 50%.

Short-size (237 ml) drinks are not included in the promotion.

Starbucks said the event is aimed at customers who want to enjoy coffee later in the day without the effects of caffeine.
