The cozy place has minimal decoration and contrasting colors like red, white and black. The menu is nicely scripted on the walls.

The place is named after Doña Casta, the merchant and the cook, specialized in croquettes and tapas in Spain. During the Franco regime, she fled to Cuba. The chef of the restaurant, Rancys Valdés, is one of her followers. The chef creates excellent combinations from meat, rice and bananas, adding onion, coriander, chili pepper and ginger.
