Gone are the days when William Burroughs could cheerfully write of the endless stream of louche offers from young boys and men around the Petit Socco. Nowadays, the busy little square in the medina is a great place to linger over a mint tea, watch the world go by and contemplate its colourful past. And sleaze remains close to the surface: you'll have plenty of offers of 'something special, my friend' and several of the cheap pensions overlooking the square still double as brothels.
