On the Dave Gorman podcast I subscribe to, every week listeners send in the names of any pun-based shop names they've seen, to be considered for submission to Pun Street - a fictional street, with one of every type of shop. Only the best puns get on the street, as they have to both win over the Pun Street Planning Committee, and then they have to remain usurped by better puns!
Anyway, if you like puns, check out the full list of shops on the street.. it's quite funny! I wish this street was real, it would be brilliant! I'm still looking out for one to send in.. I'm scuppered since they banned submissions of "The Codfather".
