You helped me with something I was looking for last month. We will be in Frankfurt soon and would like to try a cheese sandwich that we saw on something . It is a huge cheese wheel that they melt under an oven and then spread the melted cheese onto bread to make a grilled chesse type sandwich. I think they can also add other things like garlic, etc. You gave me two locations to try but now I can't find my post since they changed the format. Could you please tell me the name of those places again?
