Where to have Turkish Food One might think of the best Turkish restaurant in London when they think about last week's night out. They ended it with a late-night Kebab. Tarshish is a place where one can experience the same culinary delights as that late-night stop. The best Mediterranean restaurant in London is one of the most healthy in the world. Tarshish has a wide variety of ingredients, and they are all fresh every day. Turkey's staples are vegetables, lamb, and fish with plenty of olive oil.
