Look at the velocity profile from the surface to the line of maximum flow. A nonviscous liquid will have a very steep initial gradient from the boundary layer to rapid flow, whilst a viscous liquid will have a fairly constant gradient from edge to centre (of a tube) or surface to leading edge (of a liquid sliding over an inclined plane). A viscous liquid in contact with a single plane will have a distinct leading bulge.
