Anglesey
This was the place where William and Kate used to live during the beginning of their marriage. During this period of time William was employed as a rescue helicopter pilot while Kate was having the role of the housewife in this royal marriage. During this time, they have succeeded in having a pretty good and normal marriage and life. There were numerous reports that were talking about William jogging or Kate going shopping for groceries and similar stuff. When they wanted to relax, they used to go to their favorite put at that time and it is called White Eagle at Rhoscolyn. It was also reported that they behaved quite normally and it was seen that they are in love.

Food and drinks
During their stay there and visits to this pub, William used to drink bitter or he drank some pints of beer while Kate was usually drinking white wine or sparkling water. William’s favorite food seemed to be burger and chips while Kate used to order fish and some salads. It should be noted that the couple was never spotted in a pub with Harry and Meghan, but the reason for this may be the different lifestyle that Meghan has.

Meghan
It is known that Meghan is mostly used plant-related food in her diet. It is not a secret at all that Meghan likes  almond milk, carrots, hummus and green juice and that she also likes chia seed pudding. There have been some rumors that Harry has also transferred himself onto this diet as well. The predictions are that their children would be raised in the same manner, too, or that a child would be a vegan.

The Queen
On the other hand, the Queen surely does not like this idea and it this may have also created some tension between Meghan and Harry. The biggest problem of all may be the fact that it may seem as if Meghan is testing the boundaries in the royal family which has learned to live with certain rules and traditions during the course of history.
