In short: no, no, yes and no.

Wardrobes have been enhanced away a couple of years ago, so that you are now able to stuff your coat in the overhead bin (or depending on the crew hang it on the bulkhead if you are in a bulkhead row).

There are no welcome drinks (and LH serve no champagne on short haul) but you should get a pre-meal drink. The meal will be a selection of cold plates (salad, meat, desert) with bread warmed in the oven forming the hot component.

in terms of comparison with other Euro-business class, they are all much of the same indeed. Who still has wardrobes, for example?
