Always Sunny is Turning 21. We're having a birthday party.

It's Always Sunny in Philadelphia turns 21 this year, and we're celebrating the only way that makes sense: a bar crawl through actual filming locations in Philadelphia.

On August 1st, a small group of 20 people will walk the streets of South Philly, visit the real spots from the show, and raise a glass — including a Four Walls birthday shot at Ray's Happy Birthday Bar, one of the most iconic locations in the series.

Three bars. Three drinks. One abbreviated filming location tour. About 3 hours.

Tickets are $65 and we'll have just 20 spots.
