DAIU Cardiff Bay

You're wandering around Mermaid Quay on a Friday night, spoilt for choice amongst the usual suspects, when you clock the queue snaking out of DAIU. It's the kind of spot where families pile in alongside groups of mates, everyone tucking into endless plates of dim sum, sushi and stir-fries. The buffet format means you're not waiting around for a starter to finish before your mains arrive—grab what you fancy, go back for more, and pace yourself accordingly. It's proper casual, no faffing about with menus, just good value eating with enough variety that everyone walks out satisfied.
