I don't think such a thing exists, I've been once and the whole area around the ground seemed like a total s*** hole.
Away end is pretty s***, you are in corner and if you are near the back the view is restricted by massive metal supports holding up the roof, I didn't have a seat the stewards said Rangers fans rip them out and there's no point replacing them as they'll just do it again next time.
I'd drink in town, there are some cracking pubs. You could risk drinking around the Barrowlands if you fancy soaking up the atmosphere though you might have to keep schtum.
