I also had a mystery click when I first got my bike. It wasn't repetative with every pedal stroke. It was just one or two clicks after I'd start pedalling, after coasting or braking.
Turns out one of the pawls, which is a part inside the hub, was in backwards. This mistake was made at the Shimano factory, and I guess it's highly unusual that it would be put in wrong. Luckily, my lbs guy found it in one visit. It would have been very easy to miss.
If you have a weird click that the mechanics can't find, have them look inside your hub. It could be a pawl.
