Named after a mystical paradise in Tibetan Buddhist tradition, Shamballa offers a serene vegetarian escape. Enter through an aged wooden door to discover Tibetan artefacts and a menu rooted in Vietnamese flavours and local techniques. The rooftop garden grows the herbs used in the dishes, and the terrace overlooks the Hàn River, which is stunning at night. Don't miss the woven noodles with piper lolot – a grilled vegan dish wrapped in fragrant local leaves.
