The Alchemist Cardiff


Step into a world of theatre served, as The Alchemist has become the talk of the town on St. Mary Street. This bar and restaurant specialises in the experiential with a cocktail menu second to none. Try the infamous sharing cocktail The Mad Hatters which features mind-bending science. This vodka and citrus-based cocktail is filtered before your very eyes before releasing a plume of fragrant smoke, heightening the senses and teasing the taste buds. 

Join the venue during the late night hours. Through their 'After Dark' drinks packages, you can book a drinks table post 10pm Thursday - Saturday. Through the online booking form, choose your drinks ahead of time, saving any hassle on the night. The venue is getting a great reputation as a place to end up at the weekend. 

What's more, start your weekend right with their Alchemy Cocktail Brunch. Enjoy 3 cocktails and any brunch dish for £30, or make drinks bottomless for £10 extra. A great way to sample the delights of this creatively weird venue, plus great value.

The all-day dining menu promises to showcase breakfast, lunch and dinner dishes from across the globe, including the likes of the Pancake Stack (with bacon or fruit), Crispy Curried Fish and grilled British Steak. But the cocktail menu will rightfully take centre stage. Armed with international spirits and flavoursome liqueurs, the expert mixologists will use a range of intriguing techniques to create each cocktail. With both classic recipes and contemporary options on offer, the bar promises to cater for a variety of moods and tastes.
