Night time in Istanbul

This is my first experience walking in the street at night at foreign country. Normally when I travel to other country I never walk at night. I always feel tired after walking for hours during the day time and I could hardly move my legs at night. It is quite an experience, and the city is qiuite crouded at night and nice beautiful lights. It it quite safe in Istanbul. I did not enter the dark and lonely areas. There is quite a number of grave yard in the city with high tombs. Some even have a cafe in the centre of the grave yard.
