I don't think you will beat Derby Road area for a selection of decent pubs. Lot of pubs right in the centre of town of course and ,abe quite a bit busier, but not as nice as the pubs on Derby Road.
Another traditional pub crawl in Nottingham Is Mansfield Road:
The Forest Tavern (The Maze) - music pub
The Loft - bit deserted
Fade/Hard to Find Cafe -nice bar
The Lincolnshire Poacher - one of Nott's best pubs - real ale plae, same small local chain as Vat & Fiddle
The Nags Head - Average boozer with big screen
The Golden Fleece - decent pub with free music
The Peacock - unexeptional b
