1. Restaurants keep the temperature cool to make eaters eat more
Restaurants try to keep the ambiance dim and the temperature cool so that the customer feels like eating more and more warm food to feel warmer inside.

2. The menu is designed to make us look at their most expensive dishes first
The designers of the menu have many tricks up their sleeves. There’s a separate science behind it, they place their most expensive dishes in the middle of the menu as they know we as consumers look at the middle of the menu before we bifurcate towards the two directions of the paper in our hands.

Also, they place their slightly cheaper (yet pretty expensive) offering right next to its similar but very expensive cousin so that you end up paying a lot anyway.
3.Tables with a view are only for those who come for meals
If you are visit a restaurant just for a cup of coffee or pizza you are certainly not getting the table by the view.

4. Restaurants introduce social attractions to make you think that you’ve been eating for a longer time
These distractions make you feel like you’ve eaten a lot and been there for a much longer time which works very well in the favor of the establishments, ergo, makes you pay more for less amount of food.

5.Recipe from the chef and unusual names given to regular food
This is a smart trick they use to fool the customers, as they think that the dish is something fancy so that the price could be raised.

6.They confuse you by offering ambiguous portion sizes
It’s confusing and That’s what they want. They offer you different sizes of portions so that you chose the slightly larger one which you think has more food that the smaller one and end up paying a much larger amount of money than that portion of food, which is hardly any bigger than the previous, deserves.

7. Bringing a free lemonade with the menu
We cannot leave the restaurant even if we find the prices on the menu to be high. A fresh cold lemonade makes you hungry and want to eat something hot. This is one of the most used tricks.

8.They use corn starch paste to pass off as the cheesy white sauce
The cheesy white sauce pasta you eat so lovingly has nothing but chemically modified corn starch paste in place of your dear cheese sauce.

9.The olive oil which is apparently healthier than other oils is seldom purely olive oil
It is said that olive oil is one of most trafficked oil around the world. Which brings it under scrutiny. It is sold in cheaper prices mixed with sunflower oil and 80% of what you get is sunflower oil instead of pure olive oil.

10.Waiters can tell what customers will order based on appearance
Waiters who have been in this field for long can tell by your appearance and behaviour what you would order.
