The composite Cottage and Southern Kitchen is the best I have found in Opensim recently for working kitchens.

Some are more beautiful, but sadly, just for looks. This one actually has some good poses, and the best coffee maker I know of (the All You Need Is Love coffeemaker!).

I take this as a bundled set for my homes, be sure to get the coffeemaker in there! :)
