While I can't certainly classify this place as a true Warehouse (see also, Men's Warehouse), it is a great bar/addition to an already happening scene in Plaza Midwood.
This place rules supreme in the Spring/Summer time, as their rooftop bar is one of the best in Charlotte. I believe nearby Peculiar Rabbit also has a rooftop, but it's sans bar, so I still would give my vote to Whiskey in this particular neighborhood.
$4 Jack Daniels AllDayErrDay, which is always my go-to. Food has always been superb, and is definitely one notch above normal bar fare.
If the weather is nice, head upstairs---you won't be disappointed.
