Standing out from the crowd would be a risky route for a lot of bars to go down at the moment. There is precious little business for all to share currently, and with big suppliers practically giving away domestic beer and spirits (there are several wars going on at the moment re; Vodka, Rum and regular beers) is easier to compete with your neighbour, than re-style you business and outlay precious cash reserves.
My point being, this is the wrong time for a business to rebrand,there is virtualy little new business to attract and current stocks are being reduced in price.
I feel that most places will stick with the current business model, and work on that.
