Best restaurants in Mermaid Quay

Cardiff was recently named one of the top ten cities to live in Europe, and it’s not hard to see why. From the historic Cardiff Castle in the heart of the city to natural attractions like Flat Holm Island, you’ll never be short of things to do. There are plenty of indoor activities for colder months like museums, cathedrals and churches, cosy pubs and cafés and excellent restaurants, plus when it's warm, the wetlands reserve and Aqua Park are a must.

The completion of Cardiff Bay in 1999 was one of the largest engineering projects in Europe. The project created a 500-acre freshwater lake with eight miles of waterfront. This waterfront is now home to Mermaid Quay, a shopping and dining centre overlooking the bay.

Mermaid Quay, like Cardiff, has a lot to offer. Stop in at The Glee, Cardiff’s first comedy club, or visit the Everyman to catch a film. Those who are visiting can stock up on gifts to take home at Zia Boutique or Fabulous Welshcakes, or get pampered at the award-winning Ken Picton Salon.

Mermaid Quay also has an Aquabus waterbus tour, offering trips around the bay and beyond. The centre is always being added to and updated, making it one of the best spots to visit for food and drink by the waterside. Some of the restaurants on the upper level even have terraces where the spectacular views of the bay can be enjoyed over an Aperol Spritz…

We’ve scoped out the best restaurants in Mermaid Quay, from fancy French brasseries and secret gin gardens through to places for a quick bite and restaurants you’ll want to enjoy all day. All you have to do is peruse the list and decide what you like the look of. From brunch to burgers, tempura to tacos, pulled pork to pints, we’ve got you covered.
