There is indeed no hot towel service - you get a cold towel with your meal tray. Food can be nice but can also a bit too sophisticated sometimes. In terms of service this is indeed my biggest problem with LH (and I have not seen this in other intra-European C cabins - once food and beverages are served, staff helps serve in Y class, leaving C class without any service for quite some time. Different in OS and LX, by the way!
