Wander around Strasbourg and experience the local culture and cuisine.
August is the best time to visit for cultural events and street theatre.
As to getting familiar with the local cuisine, I came unstuck at trying their famous Alsace sauerkraut. They say you've got to try anything once, in the case of sauerkraut, once is enough in my lifetime no matter how many Michelin chefs prepare it.
Apart from that little hiccup I will recommend Strasbourg to anyone who'd like to experience the French/German melting pot.
