Marmaris, across from the Hanover train station, offers Turkish cuisine, with lamb burgers and salmon among the many choices, coming with salad and rice. There is good food, and they are very friendly and helpful, though not much English is spoken. This is just one of many vendors on the first floor of a two-floor food court.
The lamb burger was too spicy for me, but the salmon was very nice. There's seating in the area.
Their friendliness set a pleasant tone during our meal there; it more than makes up for the lack of fluent English.
