As Cambridge is my nearest decent place to go out and sample alcoholic beverages, it is top of this list!
First off is some map action to help you get around:
This map has some street names, and an author-produced rating system for each pub which on the whole is pretty fair.
This page, from Cambridge Uni I think, is a pretty good map with pubs named in relation to general landmarks.
This list divides Cambridge up into different beer quaffing regions.
This Adhoc Guide to Cambridge even features a facility! Actually, this guide is excellent, and you can search for pubs by beer name, facilities (I used it to find which pubs have table football), street name, food, or even ones which don't allow brats in them. Superb.
