Provided the weather is nice, I plan to hold this meetup in Washington Square Park, between 6th & 7th Streets on Walnut in Olde City. If you don't want to sit on the grass, just bring a folding chair or picnic blanket to sit on. You can also bring any type of food or drink you want, although I don't think alcohol is allowed in the park.
(If it looks like it'll rain, we'll move our discussion to nearby Café Walnut, right off the park on the corner of 7th & Walnut.)
The park is fairly easy to get to if you're using public transit. With SEPTA, take the Market-Frankford Line & get off at the 5th Street Station (corner of 5th & Market), and walk 2 blocks south on 5th and then turn right on Walnut Street and walk 1 block west. With PATCO, just get off at the 9th-10th & Locust stop and walk 3 blocks east. For those who are driving, parking in the neighborhood can be tough to find. If you can't find a spot on the street, I'd suggest parking in the Washington Square parking deck at 249 S 6th Street which is just a half block away.
