aaahhhh thought that would be too easy ! Ive looked for the address online and cant seem to find it, I asked the receptionist at the hotel and she found it within seconds, its at the junction of the B304 and A99 in the North of the City. Basically go up Dachauer Stasse and there is a industrial estate on the right just before the A99 (ring road) and there is a sign for Touratech.
