My main gripes with Google Maps is that it seems to work OK if you know the name of the place you are looking for, but not its location. But it really doesn't work if you know the location but not the name. If there's any clustering of stores, you can zoom in all you want but it will only show 1 in 2 stores, sometimes even fewer.

Also annoying is the sort order of many searches these days somehow giving you random residential locations at the very top. I suppose these are small webshops ran out of homes for the same search term. But that's rarely what I want to find when I'm using google maps.
