There was a big Mexican group who also stayed at the Hotel Stadt Tuttlingen that evening. And a few hours later we met them again in the restaurant we picked for our dinner. After a glorious meal (and some wine, beer, schnapppps and diet coke (!)) Angele took courage (we pushed her over) to ask if we should sing our mexican song "Chili con Carne". I think we will get some recipes from Mexico soon.
