Where are the most niche businesses?

Dave and Fionnuala have been out on the roads for the weekend, and they’ve come back obsessed with one very specific Irish phenomenon: the random, brilliant concentration of niche businesses from the Midlands out towards Mayo.From County Photos and Star Trophy to Madden’s Pool Tables and an eggs vending machine, they’re asking the big question: why are all the oddly-specific legends based along these routes?Then the listeners get involved with even more niche gems - boxty made from a food trailer in Belmullet, a salt room in Drumlish, and the people quietly servicing sanitary bins across half the country.
