I just visited three options at MSP.
PGA Lounge:
I used my Priority Pass to get a $15 credit for dining here.
As you can see you're going to be out of pocket on everything. But my turkey burger and fries were decent and worth the $7 plus tip (once you added in my soda). It's a nice place to relax too.
Escape Lounge:
This was at 2 PM. Space wise I think it's the best looking Club at MSP. I love the sweeping tarmac views, the wide variety of seating and the lighting.
Food wise I think they still have a long way to go. I'd eaten at the PGA Lounge and I'm glad I did because the quality of that beef and chicken made my stomach turn over just looking at it.
They're also a little cheap on what drinks are free
I don't like paying $5 for a beer at a lounge but that's life.
United Club:
It's tiny, one of their smallest lounges I think, but the staff are really friendly and it was nicely empty. I'm glad I popped in.
