I think this is the place – it is Grafton Street in Dublin.
When we were in Ireland in 2008 we did a bus tour of Dublin and we passed this shopping area on the way. It is one area that I would have loved to have spent lots of time browsing!
The following is taken from http://www.lovingdublin.com/Dublin-Shopping-Grafton-Street-poi-73-en.html
“Grafton Street is a shopper’s paradise and one of the most fashionable retail areas in Dublin. High street stores and designer outlets line each side of the thoroughfare, while buskers and street performers entertain the gathered crowds. Taking a stroll down Grafton Street is a must when staying in our apartments in Dublin.” PostaDay 2011
