I hear the comments about the inop toilets in ORD and DEN, but I still find it better than the public facilities - and that actually makes it worth the price of admission.

Plus, I have found CS to be much better in the lounges than outside.

I was in MSP in Nov with a colleague, we popped in after our flight from SFO/DEN (no food on either flight so the hunger meter was pretty high) and we had "after school snacks" in the lounge, checked email, went to the 'loo, etc.

And the MSP lounge has a great selection of sodas, imho.
