Serving temps for Pinot Grigio

[Julie@WineryatHome]

This is such a great place for wine info! I conduct in-home wine tastings, and was consulting for an event last night and we had a question about serving temps for Pinot Grigio - we tasted one that generally "shows" well, but the host of the event wanted it VERY chilled (straight out of the fridge) and it seemed to really dull the flavor, almost tasted like lemon water. I've done a bit of research on this, but do you all have any suggestions on Pinot serving temps? How cold is too cold? Thanks for your help!!
