The popular business The Green Line Cafe is celebrating its 10th year of “coffee, culture, and conversation from West Philly.” Congratulations to the owners, Douglas Witmer and Daniel Thut, staff and all the fans and lovers of Green Line’s brewed products and friendly atmosphere.

To mark the anniversary The Green Line is inviting neighbors and friends to a party this Friday, Feb. 15 from 4-8 p.m. at its flagship location at the corner of 43rd Street and Baltimore Avenue. There will be free coffee and birthday cake (while supplies last), door prizes, and a slide show of the history of the The Green Line. You can also help decorate a giant birthday card. For more information about this event, please contact Douglas Witmer: greenline@greenlinecafe.com

Throughout 2013, The Green Line is inviting their patrons to add photos and memories and interact with the web-based anniversary projects on Instagram and www.greenlinecafe.com.

The Green Line Cafe was established in 2003 when brothers-in-law Witmer and Thut opened their first shop at the corner of 43rd and Baltimore on a cold January morning. Since then the cafe has added a few other locations in the area and expanded to Center City last year.

Currently, the Green Line is “growing inward” – the guys are renovating their original basement to include a walk-in refrigerator so that they can supply the city with more of its famous cold-brewed iced coffee this summer.
