Large, often multilingual menu boards and pushy door staff advertising restaurants on busy main streets lure in many tourists. These establishments usually prioritise high 
sales rather than quality. The food is often expensive and poor quality, designed only for quick tourist consumption. To avoid such tourist traps and find truly authentic culinary experiences, there are a few things you should keep in mind.

How to find authentic restaurants:
The most important tip is to stay away from main streets and central squares. Authentic restaurants where locals eat are usually located on side streets. These are the real gems that don't rely on foot traffic, but on their reputation and the quality of their food.

Another clue is the menu. 
Check if it's only in the most common languages, such as English, German, or Spanish. Restaurants that cater to locals often only have a menu in the local language. 
Local language, or at most offer a simple, unobtrusive translation. A small, seasonally changing menu is another sign of authenticity. This suggests that the dishes are freshly prepared using local, seasonal ingredients. A long laminated menu offering 50 different dishes, on the other hand, suggests mass production.

Observe the restaurant.
Before choosing a seat, take a look around and see who's eating there. Are the customers mostly locals, chatting and enjoying their food? Or are they mostly tourists? Locals know where to find good food and can be the best guides.

Another good sign is the quality of the service. 
In authentic, family-run restaurants, the service tends to be more personal and warm. Sometimes it can take a while for the food to be served because everything is freshly prepared. Take this as a good sign — it means you're not eating in a kitchen designed to reheat ready-made dishes quickly.

The smell can also indicate whether a restaurant is good.
 A good kitchen will smell of fresh herbs and spices, as well as delicious food being prepared, whereas touristy restaurants often lack a distinct aroma.

Do your research in advance!
Before you travel, do your research. Use online platforms such as local blogs or food guides to find recommendations for restaurants off the beaten track. Reviews on sites such as Google Maps, Tripadvisor or Yelp can also be helpful, but make sure you read them carefully. They can often reveal whether a restaurant is a tourist trap.

Armed with these tips, you'll be well-equipped to discover a destination's true culinary treasures and enjoy an unforgettable, authentic experience.
