There are some people working on this and proposing some options.

IMO, as someone who regularly edits OSM, the maps need much more info and basic editing before reviews. I had to add many of my fave restaurants. Forget about reviews when the restaurants aren't even on there. Just saying. Maybe as it gets more users.

(Tangent: I was just in a foreign country where I didn't have much mobile data. But I had downloaded OSM maps beforehand and made edits beforehand for my trip. The only downside is that OSMand doesn't update their maps very often in some places so I almost never got to use all my edits. Overall though the offline maps were very helpful for navigation, etc.)
