Top Hole-In-The-Wall Bars in Buffalo #3
#3 Green Buffalo Pub--AKA GBP
Sometimes called the GBP, it's the #1 local watering hole-in-the-wall in Lancaster. Your friends are always there and expect the place to get rowdy with sing-a-longs by midnight. It's tradition to go after Christmas Eve festivities for a beer at midnight and the wings are killer good.
Also, highly recommended for St. Patrick's Day celebrations.
