"Alexa, what fast food restaurants are at the next exit?"
Gmaps is currently the clear winner on this. I'm using it 2 or 3 times daily while on trips down the interstates to find restaurants. Load a route in Gmaps, click the search icon twice, enter the target kws. Bingo! You get pop-ups along your mapped route along with how far it is off your route. Waze and others tend to give the geo-serp in a radius format, which has rarely turned out to be useful to me.
