FAQs on underground cocktail bars in Bath

They offer atmospheric lighting, intimate booths and high-quality drinks away from the main street bustle. The immersive setting makes them perfect for date nights, catch-ups and small celebrations without the noise of larger venues.

Book for Fridays and Saturdays, especially for groups of four or more. Walk-ins may be possible midweek or before 7pm. Ask to be added to the waitlist if the bar is full — it’s often quicker than you expect in smaller venues.

You’ll find both: expertly made classics plus seasonal signatures using house syrups, infusions and garnishes. Many bars also feature strong mocktail line-ups so non-drinkers can enjoy equally creative, complex flavours.

Smart-casual is the norm. Trainers are generally fine if the rest of your outfit is tidy; gym wear and large bags are often discouraged in the evening. Check the venue’s page for event-specific dress notes.

Absolutely — most stock alcohol-free spirits and craft softs. Ask the bartender for bespoke zero-proof serves that match your favourite flavour profile so you still get the full cocktail-bar experience.
