On a gritty street in the gentrifying San Telmo district, British expat Terry Walshe's Club 647 appeals to internationals tired of the usual parilla beef and frites. Golden chandeliers, blood-red walls, and faux antique mirrors recall 1940s Hollywood depictions of Shanghai glamour. In addition to inventive pastas such as fresh beet gnocchi with goat cheese and smoked almond butter, and mascarpone and pea risotto with pistachio pesto, there are updated classics like grilled tenderloin with mashed potatoes topped with a fried egg and shaved truffles. Porteño Santiago Giovannelli's drinks include the local favorite Malbec and soda and the more elaborate 647, a blend of rosé, port, and spiced plum juice. Reserve if you're eating late, as locals do, or stop by for an early dinner after braving the always packed Sunday San Telmo flea market (entrées, $12–$18).
