Catering for special diets and needs is the sort of attention to detail that builds you loyalty and referrals.
Let your guests know in advance if you can provide special diets or meals. Plan ahead for the huge numbers who have some kind of allergy or intolerance to certain foods. If you don’t cater for them, it’s not just their custom you will lose – their whole party will probably end up going somewhere else. You just have to look at any of the big supermarkets and their range of ‘free from’ products to recognise there is a huge market here.
