cafes/tearooms in Loch Rannoch area?

jumbolugs

A group of us are riding the Etape Caledonia route this Sunday and since we don't know the area very well I am trying to find out about suitable cafe stops. The only one I know is the tearoom at Rannoch Station (yes I know that isn't on the EC route but we're not being religious about it :P

Any info would be appreciated...

Thanks
