How young can you be and still eat at a restaurant without an adult?

@Pikachu I dunno. Where I come from a "proper sit-down" restaurant is a neighborhood Italian place, a pizza counter, a bodega with a food counter, a diner. I guess the only times I remember "kids" being at a fancier place solo would be a date. Prom or some such.

@CopperCicada

Yeah i think high school kids can get away with it

@Pikachu I really think this has much to do with demographics and geography. A small child walking alone into a branded restaurant like Olive Garden in suburbia would probably be really weird. As would a small child walking into a local seafood place here on the coast. Provided they aren't known to anyone on the staff, of course. But in an urban setting, probably not such a big deal. I say that, but I remember a case of a family who got in trouble for letting their kids take the subway alone. So who knows.
