There are lots of historic sites in Istanbul. Some offers good food along with history in humble setting. If you happen to be a tourist, these half empty tables, and chairs, will look dull to you. If you are a traveller, you know why you are here. I got all sort of soups(offal is my fav. by far) in here. Any day of a week, anytime of the day, It always taste great. They have giblet dishes as well, standard Turkish cuisine. Some French and Japanese liked these dishes, but this is not for all. You should not miss it, if you are adventurer from gut. Sweet stuff? you should finish what you started! Enjoy
