Thanks for spotting this and updating the map. Unfortunately, you deleted the whole building, rather than just removing the tags relating to the café. I have reinstated the building, changing the tags for the business to:
disused:amenity=cafe
old_name=Pink Lemonade

Using a lifecycle prefix like disused:* rather than deleting an object preserves its edit history and also means that tools like StreetComplete will periodically prompt users to check whether the premises are still vacant.
