Air-conditioned cafe in Kampot, Cambodia?

Sometimes when travelling in hot humind places you want a couple of hours respite in a nice spot with air conditioning to work out your plans, keep in touch on the Internet, etc.

Kampot is well established on the tourist map and expat maps, which usually makes such places pretty easy to find. But today all the coffee shops I could find had open doors despite the heat so I just spent all afternoon sweating.

Is there a cafe that's cooled inside that I didn't find? In the past I've asked some questions looking for places with Wi-Fi and electricty - here that's the easy part - almost everybody has it.
