Here are a few pubs in the Mill Road region of Cambridge:
The Kingston Arms
Situated on Kingston Road, on the left just before the rail bridge. This is an incredible pub, with a very friendly atmosphere and a sign outside saying 'No lager'. They usually have a large selection of real ales, but without the attendant beards. Nice beer garden in the summer, and very good meals as well.
The Salisbury Arms
Found on Tenison Road, which joins Station Road to Mill Road. This is a very large, open pub, with random bicycles hanging from the ceiling and a good indie juekbox. The beer is reliably good, making this a nice place to go on the way to a night at the Q Club.
The Live and Let Live
Within 30 seconds of the Salisbury, this small pub is on Mawson Road, and well worth a visit. Amazing beer, a truly local feel, and incredibly friendly. They also have a pub cat. They also serve some pretty nice food, and only allow smoking once people have finished eating it. They sometimes do tie-ins with beer festivals or have live music.
The Empress
On the far side of the Mill Road bridge, on Thoday Street, this is another big pub with great beer and a nice atmosphere. Often packed at the weekends, although this is hardly suprising. They also have pool and darts, featuring a board so well used that about three inches of the wall have been eroded behind the backboard...
Pubs actually on Mill Road
Personally, I'm not a fan of these, as they always seem to be crowded and only serve expensive lager. However, just after the end of the road (not that you'd notice the name change) is the Brook, which has a much more local feel and usually does a nice pint.
