Water bug might be on to something. Could it be the drain that smells maybe from a bad air admittance valve/cheater vent? Look under the sink and see if the drain line has a stub that sticks up a bit and then is terminated with a threaded cap like this. Link.
Unscrew the vent and make sure air only flows in one direction. Or for $3 just replace it and see if the smell goes away.
