When two people have been on several dates, they have generally been to a couple of restaurants together. These are usually generic places where they will not be exposed to foods they have never tried, and it is a good way for them to begin spending time learning about each other. If the relationship begins to look like it could occur, the couple might then start sharing their favorite eateries as a way to introduce each other to their background. Discovering a favorite restaurant together when they had no idea they like many of the same dishes could be an important step in cementing their relationship.
Many communities used to cater only to what the locals had, but the availability of good ingredients with faster travel times has made it easier in the last few decades for restaurants with foreign cuisines to open all over the world. People now bring their food with them instead of learning to eat what is geographically accepted by the locals. This opens a range of possibilities for those who like to experiment when eating.
Being adventurous with food is often taught to children when they are young, so those with adventurous parents are more likely to find favorite restaurants outside their own culture. If they are dating someone who grew up in a distant area, it is more than likely they have tried restaurants that are not just generic to the area. It could turn out to be a fantastic way for a couple to realize they have one more area where they are compatible.
The discovery that both of them like a particular restaurant can be a good way to begin fashioning their personal relationship on a deeper level. They could be ready to start exploring other culinary eateries, or they might find they enjoy celebrations of festivals and holidays from many other places.
