Restaurants on the marina may draw crowds with their lake-front views, but Grota gets the locals’ vote for its food. Wood-oven-baked pizzas and a mix of Polish and German cuisine fill the menu, and there’s canalside seating in summer. To find Grota, head to the Rotary Bridge from Plac Grunwaldzki, but turn left before crossing the river; it’s on the left-hand side about 150m along.
