Surprised no-ones mentioned Manchester Piccadilly yet - there are 2 bars in the station, (The Balcony Bar and the Sports Bar) nothing special but comfortable enough, and beats sitting down on the Concourse. There is also the Bulls Head very nearby on Fairfield Street, that does a good ale or two. Not sampled any of the food at any of them though. There is a pretty decent pub literally underneath Manchester Oxford Road - The Thirsty Scholar - back in the days of the 23.32 departure from Oxford Rd to Crewe, was a very nice way to spend an evening. You can hear the trains thundering over the viaduct literally above you.
