San Izakaya (三居酒屋) is a highly popular, low-key Japanese hidden gem located in Puchong, Selangor, celebrated for its intimate ambiance, cozy retro charm, and warm hospitality. Operating strictly on a reservation-only basis due to its limited seating capacity, this neighborhood tavern requires guests to book in advance and even type in a password at the door to gain entry, reinforcing its exclusive, hidden-gem mystique.
