Opposite the train station
The cafe bar at the Showroom Cinema, opposite the station, is an excellent place to chill out. Massive selection of different types of food - Sunday lunch, sandwiches, pizzas, tapas - and great atmosphere. And free wifi to boot.

If you're around Broomhill, check out Nottingham House. Deals on real ales, which are £2.40 anyway (four pints for a tenner!), and original home-made pies. Not for you if you don't like pies though — it's all they serve!
I can recommend the Sunday Roast Pie: roast chicken, stuffing, vegetables and a Yorkshire pudding, all baked into a pie!
