Stay Tuned offers three things: a great, unusual gin produced in small batches, rye whiskey, and a single malt scotch so good I am still thinking about the sips I had an hour later. The rye and whiskey are brought in and the gin is finished on site with local ingredients - the staff is really knowledgeable, able to suggest why you should consider using a better, old-style tonic for your G&T, and help you understand the flavors that make their spirits so interesting.
It's not cheap and it's not right around the corner for most of Pittsburgh, but if you want something out of the ordinary that's really, really good, it's worth going out of your way.
