This is one of the top worries that rankle first time vegetarian travellers when they plan a trip to Europe or for that matter, to any foreign country. A hot piping plate of dal chawal, chapathi – sabzi or at least curd rice is a must for most of us at least once in a day, even for the hard core non-vegetarian amongst us.
For lunch and dinner, to get the authentic backdoor experience, try the local restaurants, but before you order,make it very clear upfront that you are a vegetarian and do not eat meat, fish or eggs. In Europe, being a vegetarian means you do not eat meat, but you do consume egg and fish;fish and eggs are not considered non-vegetarian dishes. Lookup Google Translate for the words “no chicken”, “no fish” and “no eggs” in the language of the country you are visiting.
