I quite enjoy Motherland. The location of the shop seemed familiar. Googling locations brings up the school involved in Chiswick but no mention of the shop. The last five minutes of the last episode convinced me though; its set in Zebra ceramics opposite the Maid of Muswell pub on Alexandra Road(im pretty sure) The irony is that its just the kind of shop that the sitcom lampoons!
Well spotted. Motherland is, like, 100% realistic.
