Restaurant searches are about the craving and the moment: 'tacos near me', 'brunch', 'pizza open now', 'Thai food', 'best burger'. Distance counts for a great deal, because nobody drives forty minutes for lunch.
Hours are critical. A diner who turns up to a closed door after Google said you were open doesn't come back, and an 'open now' search depends on the hours Google has for you.
Photos and reviews decide the rest. Customers post plenty of their own pictures, and a restaurant that adds recent, good-looking ones of its own keeps some control of the first impression. Reviews arrive in volume, and replies show someone is looking after the place.
