The area around the Munich central station is not known for being particularly interesting for tourists, this is however not true and you should experience it as soon as possible.
There is a place I really like to take friends to which is called Sara Grill House. The restaurant recently got completely redesigned.
The menu is quite simple and consists of two pages, so if you are with more people you can actually try everything. What I would recommend is to try the lamb kebap – it is really amazing. Have some of the homemade bread, which tastes exceptional. Also order some hummus and spread it on the bread. You will love it.
What I also like to do when I order the kebap is to put it in the bread and use it as a wrap. As you get a lot of vegetables, you put them in the wrap too and you get something amazing.
Also, keep your eyes open. The place is visited by some characters and it is really interesting how people from a non-German culture are integrating it in their lives.
Now, I have heard a lot people saying that it is a Lebanese restaurant, but it is actually typical Iraqi food.
Also, you can buy the Arabian bread for 50 cents a piece.
