I'm seeing several mentions online that Montgomery County's ABC stores have stocked it - I'd try calling the Rockville Pike shop to see if that's actually the case. posted by ryanshepard at 6:41 PM on June 25, 2012
I've never noticed it in DC's finer liquor stores. In fact, the only place I've ever seen Paddy was behind a bar in NYC. It also does not appear to be on the Virginia ABC list (at least not properly categorized as Irish whiskey in the regular or special order lists). This year old Yelp thread says it's available in Montgomery County, so that looks like your best bet. You can also try asking Joe Riley at Ace Beverage. I don't think he carries it, but he generally knows what's available for order.
If none of that works out, try asking bartenders at the Dubliner, the Irish Times, the four P's, and so on. Somebody at one of those bars is likely to know if it's even obtainable here. If you order something first and tip well, the bartenders will be more likely to try to help you if they don't know themselves. posted by fedward at 8:38 PM on June 25, 2012
