The competition in these two markets should be different, aiming at different customers. Cooking western food will not affect the dessert market, so the answer is that both are the same. If you think there is too much competition for western food around you, then desserts can of course monopolize the surrounding markets. But if you are surrounded by dessert shops, restaurants will of course monopolize the market. But this does not mean that the same industry cannot compete. If you can find the market loopholes around you and develop new markets for them, you can also profit from them.
