Just around the corner from the central station, this restaurant café of the Ludwig Museum offers a surprising lunch deal. For under 10 euros, we enjoyed roast pork with lashings of sweet savoury sauce served with delicious roast potatoes. The meal even included one non-alcoholic beverage. On a sunny summer day, diners can sit out on the terrace which is tucked away in the back of the museum. Despite the proximity to the station and the heavy traffic, the restaurant provides an oasis of tranquillity. You don’t need to pay museum entrance fees to lunch here.
