Echo the sentiments regarding Broad Marsh, it's simply terrible, an ugly carbuncle and an embarrassment to the City of Nottingham.
It's interesting to note the urge to create new retail premises in the city centre when it's clear that few areas appear to be doing well, for a number of reasons. Take a look around at our once fair city which is apparently, somewhat amazingly, in the top few cities in the UK we are told.
Broad Marsh - poundshop city.
Hockley - a lovely and characterful area that the council are doing their best to empty of trade with their road systems and parking fees..
West End Arcade - closed as a thoroughfare due to a dated and apparently dangerous escalator. Shop owners reporting huge loss of business.
Trinity Square - as mentioned here unfeasibly ugly with long-term empy shop units.
Flying Horse Arcade - just a criminal act
Chapel Bar - tacky looking bar/restaurant land
Market Square - one remaining significant business in Debenhams (who would clearly like to move out)
I always liked Nottingham's city centre, I really did, but is has been ruined year on year, decade on decade. It would be easy for any visitor to view it merely as an evening weekend warzone with a dated '70s shopping mall containing predictable chain shops.
