Our Story

A Cardiff Institution

Castello Grill House was born from a simple belief: that great food starts with exceptional ingredients and an open flame. Nestled in the heart of Cardiff, we've been serving the finest cuts of premium British and Irish beef, cooked over wood-fired grills to bring out flavours that speak for themselves.

Family-run since day one, we combine the warmth of Welsh hospitality with a passion for the craft of grilling. Every dish that leaves our kitchen carries a commitment to quality that our guests have come to trust — and keep coming back for.
