If he’s traversing the city and has a restaurant suggestion from a Jelly, he may have to cross the city and/or travel a lot to find the restaurant. My suggestion, which is for anywhere one travels, is to look at menus in windows, and for him to see what he feels like eating at the time. It wouldn’t be practical for him to spend lots of time and money crossing the city in order to find a place that’s supposedly good and to save a few bucks on food. Plus restaurants in a city like SF change so often, as they get evicted, owners change, etc., that what’s around probably changes so often and so quickly.
