it was not very clear since the beginning, but now I found out:
1) 1 building with number 98 -> shop Retro Arcadium: https://www.openstreetmap.org/node/4639656921
2) 1 building with numbers 104 and 106 AND with 1 entrance: 104 is the Brussels Pinball Museum (https://www.openstreetmap.org/node/8911942740) and 106 is a pub that belongs and is directly connected to the museum
-> the 3 amenities (shop, museum and pub belong to the same person/operator)
-> can you still have a quick check if everything is correctly mapped?
