Tiel'O is a wine bar in Gangnam, Seoul, serving wine and Italian food. It moved to Gangnam from Sinsa and offers truffle cream gnocchi, fresh pasta, and tenderloin steak that is sliced and grilled to order. The space has an open kitchen and an in-store wine cellar, and a sommelier explains the wines and suggests food pairings. Corkage is free at lunch, and free in the evening when a bottle from the venue's wine list is ordered.
