Great to see some new mapping taking place in Evesham. I do visit
occasionally and last year did some updates around the centre.
Unfortunately I haven't had much time during recent visits.
Tagging multi-level buildings can be difficult and there isn't one
agreed way to go about it. Generally I would try to keep it as simple as
possible while adding the information you consider important.
The easiest option in this case would be to place a node inside the
existing Town Hall building outline. Tag the node as a cafe, add the
name and other details as you wish. Also add level=0 to show it is on
the ground floor.
A somewhat more complicated approach would be to add the outline area of
the cafe inside the town hall building. This would probably cover the
whole of the building, except for the access to the first floor. You
could then tag this outline as a cafe and again include level=0 and
other details.
The Town Hall is currently mapped on this way:

It might be worth changing the name from 'Town Hall' to 'Evesham Town
Hall'. The address could also be added.
I hope this helps,
