I do not recall which location I visited as I'm not from Pittsburgh. However, if the chain is as good as the location that I visited on my trip, then we all will benefit.
I stopped at a local liquor store with a group of friends and instantly was turned off by the sectioned off lines and long counter. You had to wait in line to be serviced and had to ask for what you wanted by name. We ran out of there. We came across a Fine Wine and Good Spirits and was instantly impressed. Relaxed vibe, non pretentious staff, no liquor or wine snobs about, tastings at the door and a vast selection calling you by the strategic marketing, fancy labels and colorful juice, reasonable pricing. I was in heaven. Their range included options for groups/ semi-bulk purchasing, individual purchases and on the go pre gaming, personal selections (I bought a miniature Goliath red moscato box wine!)
I have to book mark this place as the only place to go when in need of libations while in Pittsburgh. Highly recommended!
