OTPH is a great Cornelius option. Kenny is an outstanding bartender who knows how to create ambiance and conversation in addition to always keeping your drink filled. They have items on tap and have some unique can options that change frequently, including a sour or two.
They have a range of various local music and will change the art on occasion. They also keep a few games like shut the box hanging around.
They're a smaller more intimate spot, but a great stop to grab a drink and chill without worries.
