Brick Sand Gangnam Station Branch is a bakery next to Starbucks near Exit 6 of the Shinbundang Line at Gangnam Station, selling brick-shaped financiers. The signature Amond Brick is crisp on the outside and moist and chewy inside, with flavors including Ruby Brick and Dark Brick. Customers can choose from several colorful bricks and take them out in gift packaging. Because the store sits in a subway corridor, visitors may wait in line.
