Leave Dish / keyword blank to sweep every restaurant. Fill it in (e.g. "biryani") to search Google Maps for that term instead. That finds places Google associates with it, not a menu guarantee.

Each map call costs 3 Serper credits (about $0.003 on the $50 plan). The sweep covers the circle with small map rectangles at street zoom, where Google Maps shows every place, and splits any rectangle that overflows. Big empty areas are skipped with a single coarse check.

Every rectangle is saved on the server for 30 days and shared by every device and the overnight crawler. Re-searching ground that is already covered, at any radius, costs nothing. Use Force refresh for live data.
