Well I work at the airport, and have been to quite a few places in the city, here's what I can think of off hand.
South Philly Tap Room. Been there one afternoon a few years ago after work, probably before a concert or a game. Small, I think we sat outside curbside. Typical south Philly feel, which is cool, but not the first place I'd go in the city.
Mo
nk Belgian Cafe. 16th and Spruce, downtown and close to Rittenhouse Square. One of the premier places in the city, certainly a fixture in the beer scene. Good food, great beer. Almost always have La Chouffe and Chimay and a ton of other greats on tap. Two bars (one in front and one in the back), very cool vibe in both rooms. Some people swear by the mussels, me...meh. Burgers are good.
I believe Yooper might have been refering to Eulogy above.
Eulogy Belgian Cafe is a very good Belgian beer joint in Old City Philadelphia (the part of town that was the backdrop for our founding fathers). I love this place, and always try to drop in here when I'm in the area. Similar to Monks, Eulogy has fairly typical belgian beer cafe food, but the beer is why you stop here. There's a very cramped downstairs and a equally cramped upstairs with an extra room. This is walking distance from Market street, Tin Alley (cool acoustic music room), and lots of interesting restaurants. BTW, the Triumph Brewing Co is probably the brewpub Yooper refered to that's nearby; been there...avoid.
Near the Art Museum and the Franklin Institute is
The Bishops Collar. It's been a few years since I've been there, but I've been a few times. Great beer menu, good to very good food menu. Again close enough to the museum and Franklin for it to be a stop before/during/after those places. Plus it's right down the street from Eastern State Penitentary, a cool old prison (featured in the movie 12 Monkeys)
Moving east along Spring Garden st is the Pro
hibition Taproom. Never been, but I've heard great things about it. Maybe I'll head there today after work...I see they have Nugget Nectar on tap :rockin:
Moving east head to the Northern Liberties/Fishtown area. This is probably what Hoppyhippo is refering to. Urban Hipster feel to this area, and I don't mean that in a derogatory way. I love Fishtown, and I'm old (relatively). I'll just touch on a few, but everytime I am in this area I see another corner bar that "probably" would be a cool place to drop in on.
Kraftwork Bar
Johnny Brendas
Barcade. great beer, old school video games...
Frankford Hall. Never been in here, there's always a line.
Fette Sau BBQ. Right next door to Frankford Hall is this BBQ joint. Fantastic Bourbon menu, and always a few great and interesting brews. The food is very good, but not the best BBQ I've had. Usually a line.
Further up in Fishtown is the
Memphis Taproom. I love this place, and although it's kind of up and away from the other stuff in No. Liberties it's worth the trip. Beer garden next door, very good food and great beer. The owners have a few other joints in town, maybe I'll fish them up and post them later.
Ok this should get you started. Enjoy Philly, it's really a great city. Lots of arts (the Philidelphia Orchestra is one of the top 6 in the world, that's no ****), lots of theatre productions always in town (Book of Mormon opens very soon for a summer run). Phillies, Eagles, 76ers, every major rock and country tour comes through this town. If you can't find something to do...you just ain't lookin'!
Oh yeah, I didn't even mention Manayunk or the University City area...
