I've never heard of any vegan places over that way. I work in Conshohocken and if I need food I drive to Whole Foods, or Baja Fresh.
There's a shopping called 'Andorra Shopping Center' that's down Ridge Pike on Henry Ave that has a Machismo Burrito ( I've yet to go to but will try with the Groupon I bought the other day) what has vegan options. Hope that helps.
