There's the so-called Bam Bam BBQ, a very small restaurant with Greek BBQ specialties, located at Hafengasse in Ulm, Baden-Württemberg, Germany.
It is located in a hidden corner, but the fine aroma of grilled food is a guide to recently opened grillroom 'Bam Bam BBQ'. They have unbeatable price-performance ratio, it is very delicious and inside is always a good mood. Food is quickly prepared, the drinks selection is excellent.
