Po'Boys   Summer 2015   There was more than a hint of the Deep South at this good-looking Vauxhall pop-up - its food is inspired by the food of New Orleans. It takes its name from the traditional Louisiana sub, but that proves an homage rather than direct inspiration - the menu here is a set, five-course affair.  Po'Boys kicked off with jalapeno panko 'poppers' stuffed with three different cheeses, followed by pickled crawfish in Cajun spices with toasted sourdough, BBQ ribs with a Dr Pepper dipping sauce and then 'wenny's big mamma gumbo' - a chicken and smoked sausage gumbo with hushpuppies. And to finish? Mississippi mud pie and coffee brewed with a splash of bourbon.
