Old Town, Düsseldorf
Since Uerige is a tourist stop of the highest order they also sell souvenirs. There is a glass case from which you choose from amongst the beery goodies.
What to buy: Alt bier glasses and beer mats are probably easiest to transport but there are lots of things to buy including swing top bottles of the world renowned beer.
Senf (engl.=mustard) is one of the specialities from Düsseldorf. One of the most famous dishes from here is made with Senf, (the Düsseldorf Senfrostbraten= a steak with a mustard and onion marinade). So the stuff is called Löwensenf (lionsmustard) and we eat it extrascharf (extrahot). I think it would also make a nice souvenir, buy it in a supermarket or at the special shop, they have nice glasses that would do for a gift.
