been GF for more than25yrs and aye it was hard tae start but wi the like o Tesco doing gf food it has become easier . as im no in the uk now I don’t know about where and who does gf meals BUT one o the best I came across was the café on Kingston industrial estate at Carlisle did pies an mash etc all gf food as well as normal.
what about the fresh baked bread and make your own snap up wi fresh meat,veg.remember most beer is a no go! I find coors light is acceptable for ME…gf lager is available but I would rather lick my boots 
.
REMEMBER GF food contains more stodge etc than normal food ,with all that brings,(bone density),sugar levels are higher.(this from my doctor when he found out the length o time I have been gf.) james.
