Cities are secret places, where paths and narratives cross, journeys are interrupted, the miraculous and the strange can appear and dissolve before your eyes. This show doesn't take place in a theatre but in the streets and alleyways of Edinburgh's New Town. "These can be mean streets" warns our guide, but the only real sense of danger is that you might be mown down by a Fiat Uno or laughed at by small boys when you shuffle along blindfolded between Rose Street and George Street.
Highway Diner wants to be different, and it wants you to see the city differently. Both are noble intentions, but the execution is shambolic, and both the script and its delivery are banal. The show lacks shape and any real sense of direction of its own and, although it offers some surprises in the glimpse of leaping bodies or the notices pinned to shop windows, most of the drama is incidental, coming from the city and its passers-by. In more experienced hands, this could have been a real theatrical adventure but for much of the time, I felt like a tourist being herded around by an inept tour guide.
