I love travelling, but I have some allergies, (eggs, onions,and dairy) and intolerances,(some spices, some seeds, MSG(especially), dextrose and artificial sweeteners), so I have to be very careful what I eat or could be in pain/discomfort after eating some foods. A reaction makes me feel ill, my family anxious and the chef worried. Greek food suits me very well and the chefs are obliging.
I must be ultra careful, but it doesn't stop me from travelling abroad and for many years I had to travel for my job. I worked in many cities in China, Macau, Hong Kong when it was still under British rule, the Middle East and all over Europe. I had Ensure in the suitcase just in case there was nothing I could eat. So you see, we're not all being small minded when we can't eat the local cuisine.
On a lighter note, in China I was entertained at smart restaurants, and the organiser always took care to order some dishes for me. On one occasion, she announced, 'This is for you Sally, weeds from the Yangtze.' 'Surely you mean vegetables Ms Yu?' 'No, they're weeds.'
