I'm familiar with the Blue Devils, quite popular!! Next time you come this way, give me a heads up and perhaps I'll be free to show you some of the shops. There are 4 right here - 1 in Danville, 1 in Concord, 1 in Lafayette (my fav!!) and 1 in Martinez. then there is one also in Berkeley and Alameda, but those are too far for regular visits!!
