A number of different suggestions in no particular order, mostly of places to add.
Some more outdoor Cafes
Seafood Restaurants
Restaurants that focus on Mordentish, Borcan, Richemuloise, Lamordian, or Darkonese cuisine, maybe some from Sri Raji and Sourgane?
Aquarium - 5e mentions there is an aquarium
Hospital - this would be a mundane doctor place focusing on well medicine. It could also offer another place to get healed(though not raised), healing supplies and hospital rp
Auberge de la Premere - This is a canon inn not in the city. It offers no food but does offer good Quality rooms. could be similar to either the manor retreat or novaks
street signs with names
more Ouvrie places for commoner rp. Perhaps one that honors past poor people and with the uniforms of the People's National Army on the wall.
For the Rue de Soliel to be like it is described in the Gazetteer going from the cathedral to the Palais
The Navigator's Bliss - an observatory used by the Celestines
The ambassador buildings
