Le Provencal

Cosy and classic French restaurant
Noteworthy for: Located in the reconstructed old town of Nikolaiviertel in Mitte, this is one of your best bets for good food in what is the heart of tourist land.

Sitting delightfully on the banks of the River Spree, this place does get busy, but that's as much to do with the excellent food as the convenient central location. Though that means you will pay a bit more here than in other less-commercial areas.
You'll find standard favourites like French onion soup and confit of duck, but also some interesting variations. Look out for the pepper steak or shrimps with pastis. The seasonal specials and set menus are a good bet too. If the weather is fine, take a seat on the terrace and enjoy the scent of the potted lavender and rosemary as you eat.
