Dear имя собседника,
Thanks for your letter. It was great to hear from you.
First of all, in your letter you wrote about the best meal you had at the restaurant last week. As for me, the best meal I have ever had is some kind of the cheesecake, which I tried in the famous restaurant in London. I can't single out one favourite food, I like different dishes and I also like trying something new. As for my least favourite foods I can say that it is fish and mushrooms. I never eat this products. To be honest, I hate them. I like cooking very much. Most of all I like to cook different cookies, cakes and pies.
That's all for now.
Write soon.
Best wishes,
Ваше имя.
