Bright, refurbished city-centre spot with kids' menu, high chairs and fast, patient service — lively at weekends, so book ahead.

Asian · Cardiff
A city-centre stop for a fast, cheap feed when the children are past waiting — you pick a base, toppings and sauce at the counter and it lands in minutes, which matters when someone is melting down. Portions are big and filling, so smaller appetites can share; the duck spring rolls and the beef with broccoli in teriyaki get the most praise, and the whole menu is halal. Staff are patient with questions, happy to talk you through how the build-your-own system works and what sauces suit. There's a kids' menu, high chairs and room to get a pram in. Fair warning: it's casual and canteen-like rather than a lingering lunch, the music can be loud in the evenings, and it's hit and miss — the katsu in particular divides people.

A little something creative for your next meal out. Filled with colouring, simple drawing prompts for cute animals, origami and conversation starters designed to bring more play, laughter and connection to the table. 3 free printable packs for toddlers, preschoolers and primary-aged children.
