I agree with Alan.
Singl-End is a very good cafe (although it gets busy) not too far from Waterstones as is Cafe Smile (Italian)
The Good Spirits Co on Bath Street is definitely a better option than the Whisky Shop in Buchanan Galleries in my opinion - not exclusively Whisky but still a large and interesting selection and very helpful and knowledgeable staff.
I'm sure there's another independent whisky shop in the area which I can't remember the name - perhaps around the West George St/Nelson Mandela Place area - maybe someone else knows the one....
Oliver the one you are thinking about is in W.George St in between Wagamama and Sarti’s.
It also specialises in Fine Cigars and Gins, Robert Graham’s.Edited: 14 May 2018, 01:02
