they have systems like this in san francisco too except they're VC funded at great expense and so they actually work, or at least they do now. I imagine they'll stop working in a few years. i think there's a great joy in going to a restaurant that turns tables quickly, keeps you on your toes, there's a ramen place I go to where you sit down and order on your phone and then they have your food at your table in five minutes. since you paid up front you can just leave when you're ready.
whole ritual of chasing someone down to give you a check is the worst part of dining in the US, absolutely uncivilized, absolutely hate it. The way it works here is, you flag down a waiter, ask for the check. five minutes later, they give you the check. you put your card into the little envelope. five minutes later, they take your card. they run it there, and then five minutes later they give you the receipt, which you have to sign and tip on. by this point your legs are cramping because you've been in the same place for so long.
