In reply to Sam Beaton:
Most restaurants are well set up for GF nowadays.
Of particular note on ecclesall road are The Cats Pjamas and the Lost and Found : both have good GF labelling and options for altering meals to GF alternatives.
There is a chippy at banner cross that does GF fish and chips too.
In the centre the blue moon cafe, which is veggie and vegan, has lots of GF options: their GF chocolate cake is lovely!
