Try The Walk Cafe, 12 Bridlesmith Walk, Nottingham. All wi fi'd up, fresh ground coffee, china teapots, fantastic cakes, a quiet garden space in the centre of the city and best of all fantastic friendly staff. Open 8am to 8pm
This is a good question ... I sometimes go to Lee Rosys Tea Room in Hockley and Starbucks or Costa on Wheeler Gate (off Old Market Square) ... I am new to Nottingham so I will definitely check out some of these suggestions.
Edin's is a good place to meet, great coffee and free wifi if you go ask for the code.
Broadway next best - better for lunch.
The Walk can be good - but pricey.
Rosy Lee's good for meeting for tea.
Jaz Cafe nice to meet with a garden - but no wifi :-(
