Because Dubai is close to the seaside, their locals should like seafood very much. There are many kinds of seafood there. You can see sharks, octopus, king crab, lobster and so on in Dubai's vegetable market. Many of them have never met, and some have never even heard of their names.
Dubai people used to hunt for a living. For decades, red dates have been one of the main local foods, with rich nutrition and good health. Arabian pie is also one of the favorite staple foods of local people. Tear a cake and wrap it in barbecue and vegetable salad. It's delicious. There are all kinds of exquisite desserts, which are also their favorite.
Although Dubai is located in the Middle East, it has everything, and you can eat dishes from any country you want. As long as local tyrants in Dubai want to eat food from other countries, they just need to fly by plane.
As described in the romance novel Marisol, I wake up every day in a 200-meter-wide bed, drinking 82-year-old wine just flown in from France in the morning and eating a big meal cooked by Michelin restaurant chefs. As for what they like to eat, it depends on their own taste. It's really poverty that limits my imagination.
