Mainly self catered but had a nice meal at the Bridge Inn Acle, they do a separate GF menu. Also at Acle is Pedro's, in one of the boathouses by the bridge. Did not try it but earmarked for future as they had lots of GF marked on the menu.
Had a superb meal at the Waveney house hotel in Beccles, lots of GF items on menu. And a GF cream tea also in Beccles, can't remember name of tea room but I will find out and post. In South Walsham we had a nice lunch of jacket spud and salad at Fairhaven gardens, they do GF cakes as well.
