None of us around here really need an excuse for happy hour, but it’s always a good thing when there’s a cause involved. All Day Buffet’s third Cause For Drinks happens tonight in six cities nationwide — NYC, New Orleans, Minneapolis, Austin, Seattle and Annapolis — each raising funds for select charities. Your city not on the bill for the night? Drop the kids at ADB a note and they’ll get you in the next lineup. More info here or on their Facebook page. Bottoms up.
