Well, Trophy bikes is *the* place for folders in Philly. He may or may not let you watch it or make you feel home there. it depends on what time you go there , if it is crowded , it has the feeling of a very commercialized place, if it is not so crowded , then they will chat with you etc.
but you could probably just go to any other LBS and get decent help on your bike. where you are near in Philly?
