I popped into Which Wich on a weekday afternoon, almost empty. Having never been there before, I went to the ordering station - read a bunch of signs, wrote on a bag, and still completely bungled my order. So the guy just took my order audibly like Subway.
I had a wicked sandwich - a bunch of seemingly random sandwich ingredients stuffed in a sandwich. It was good, flavorful, not as unique as I'd hoped, and a bit dry, but I'd totally have it again!
