Superb Bay location

Situated in the fantastic waterside development of Mermaid Quay in Cardiff Bay, why not pop down and enjoy alfresco drinking and dining with unspoilt views across Cardiff Bay.  By day, enjoy drinks or a leisurely lunch with friends, and at night get ready to party the night away with our in-house DJs.

We love cocktails is our tag line in SALT, and we offer some awesomely mixed drinks with premium spirits, fresh fruits and purees. What's not to love?! Of course we also have an extensive premium draught beer range and an enviable wine list to suit all tastes.


Looking for a gift for that hard-to-buy-for friend or relative? With our Brains gift cards you can give them the perfect present. Load them up at the bar with the value of your choice* and let your friends and family enjoy food, drinks or even a night’s stay at a Brains Inn of their choice.

Or maybe you know a budding beer enthusiast who would like to add to their collection? Our very own Brains Craft Brewery cans and original Brains Beers are now available in gift packs. Cheers!

*Minimum top-up value £5. Terms & Conditions apply. Visit for details.
