Starbucks is serving a limited-edition luxury afternoon tea in Tokyo, Japan – and it's so popular that the chain says it may have to hold a lottery to decide who gets a spot.

Starbucks' afternoon tea is called the "Roastery Pasticcini Flight." Pasticcini is the Italian word for colorful bite-sized cakes and sweet baked goods.

Starbucks' afternoon tea includes eight types of pasticcini and three small savory items, such as savory scones. It also comes with a pot of Teavana tea from a choice of four types: pineapple tea, hōjicha green tea, strawberry oolong, and a citrus, lavender, and sage tea.

The afternoon tea costs 4,620 yen ($42). A standard tall cappuccino will set you back around 418 yen ($3.80) at a Starbucks in Tokyo, roughly the same as US stores.

It's only being served at one location: Starbucks' Tokyo Reserve Roastery, one of the chain's six larger flagship-style stores.

The other Reserve roasteries are in Seattle, Chicago, New York, Shanghai, and Milan.

The 32,000-square-foot, four-story upmarket store sells espresso martinis, cream sodas, and whiskey. It also houses a Princi bakery that serves breads, pizzas, and salads - as well as the cakes from the afternoon tea.

The afternoon tea launched on July 7 and is available from 1 p.m. to 5 p.m. weekdays. Starbucks says that it's so popular that it can't keep up with demand, and will hold a lottery for spots on its busiest days to make sure it has enough ingredients.

Starbucks launched the afternoon tea to celebrate 25 years since it opened its first store in Japan. It also launched a unique frappuccino for each of Japan's 47 prefectures, such as a corn, white chocolate, and cornflake frappuccino available only in Hokkaido, and sweetened soy sauce, coffee, and cream frappuccino that you can only get in Chiba.
