It's probably the single one time where I would actually want ads.
For example roaming the city at 4am on a Saturday and trying to find some place with hot food. Google failed miserably at this. Eventually I found something but just because I knew it was often open at night. It was also marked open on Google Maps but never came up in searches there. Probably other places paid Google more for a listing despite being closed at that time.
Not sure how Apple does with this as I don't have any Apple anymore except a work iPad. It's too limited for me in terms of what I can install. But there's certainly some room for improvement in mapping.
