For a light dinner with good beer and many whiskys to sit and discuss I would go to Musa… best to book a table as it can be busy.

The Grill does have amazing whiskys but it’s a very old school pub – one to visit after you’ve eaten.
Unfortunately Blackfriers, The Prince of Wales and many other pubs are now owned by a company that thinks it’s acceptable to churn out the same bland food in all its establishments while peppering the tables with assorted special offer cheap drink leaflets… sad times.
