Our favourite outpost of Happy Pills is the shop on Calle Arcs (there at three outposts in total), where those who entered with clouds above their heavy heads leave elevated, pills in-hand. Fortunately, the pills are just sweet candy and not something more sinister, but we still like the offbeat drug styling of the bottles they come in. The price of the pills available for purchase depends entirely on the size of the bottle you plump for – choose from small, medium and large – so customers simply bag up and buy. Highly recommended are the Choco Pills, like Smarties for grown-ups.
