Whether it's Selfridges department store, or a little cafe in East London, you are never far from a gluten free, dairy free, or some other type of food intolerance catering establishment in London. The choices are so wide and the taste and flavour so good these days that it really is the place to be if you fancy just trying something new. If you really do need to avoid gluten, even better, these places have been tested, certificated and checked again and again. Many of them also use organic ingredients and make everything from scratch, and many of the places are also exclusively gluten free so there should be no danger of contamination. Check out the Happy Food company in East London or mail order from Rebel Cakes or Peace of Cake both based in North West London. If you are with friends who don't have the same intolerance, then you can go and hang out at Claridges and just order ahead telling them the list of your tolerances and they will rustle up a special menu which will make you feel like the queen that you feel when you are taking tea for two or three or four at Claridges. In Camden, Cookies and Scream provides you with all your biscuit needs and in Kingston, the Healthy Cook Company will keep you coming back for more. Suzzle in Brick Lane and Vitao in Soho are also great taste sensations and happily gluten free. Enjoy.
