I have to take a friend and her son out for dinner next week as she did some singing on dp's album for free. He son is 15 and coeliac and although i am pretty aware on this I am not sure which of the high st chain types are best. I am in Brighton and we have most chains here Any ideas. there will be 7 of us 3 teenagers and one of them as I have said is coeliac. TIA x
