Brunswick is nice although often a bit full. I dunno if they do food.
Brewery Tap is nice too – it’s the Derby Brewery pub, so it does nice beer. They also do beer and cheese, which is a nice combination. They do nice enough food but very much of the chips and things variety.
If you want a fancy meal, Zest is quite nice in a very English way. Ebi Sushi is supposed to be a very good but not cheap sushi restaurant (big Toyota factory in Derby, hence good Japanese food).
If you want dodgy drinking curries, London Road near the station has some (not very far from Pride Park). This one is actually quite okay: http://www.everestderby.co.uk/
If you had a whole free evening, you could drive up the A38 then A6 to some lovely riding in about half an hour.
