On Wall Street, fortunes are often won and lost with the tiniest advantages. And for the past few years, one trading firm has stood out from the rest for both huge profits and careful secrecy — Jane Street Group.

But last year, one of Jane Street’s biggest and most lucrative trading strategies was unexpectedly revealed in a Manhattan courtroom. The news ricocheted around the world. It drew the attention of competitors and regulatory agencies, destabilized billions of dollars worth of trades, and called into question some of the most fundamental strategies in global finance.

Ruthie's Table 4

Ruthie's Table 4

For more than 30 years The River Cafe in London, has been the home-from-home of artists, architects, designers, actors, collectors, writers, activists, and politicians. Michael Caine, Glenn Close, JJ Abrams, Steve McQueen, Victoria and David Beckham, and Lily Allen, are just some of the people who love to call The River Cafe home. On River Cafe Table 4, Rogers sits down with her customers—who have become friends—to talk about food memories. Table 4 explores how food impacts every aspect of our lives. “Foods is politics, food is cultural, food is how you express love, food is about your heritage, it defines who you and who you want to be,” says Rogers. Each week, Rogers invites her guest to reminisce about family suppers and first dates, what they cook, how they eat when performing, the restaurants they choose, and what food they seek when they need comfort. And to punctuate each episode of Table 4, guests such as Ralph Fiennes, Emily Blunt, and Alfonso Cuarón, read their favourite recipe from one of the best-selling River Cafe cookbooks. Table 4 itself, is situated near The River Cafe’s open kitchen, close to the bright pink wood-fired oven and next to the glossy yellow pass, where Ruthie oversees the restaurant. You are invited to take a seat at this intimate table and join the conversation.
