Down in South America, coca means a very specific thing. You know, that thing that gave Coca-Cola its name. But up here in Pittsburgh, namely Lawrenceville, coca is for Coca Cafe which, as far as I know, has no connection to cocaine. Instead, it seems to be very connected to brunch. So, with little concern for accidental drug use, we braved the 45 minute wait and got ourselves in for a little Sunday brunch.
