Cognoscenti Coffee, which Yeekai Lim launched in 2010, has already found success at Atwater Village’s Proof Bakery and with a stand-alone venture in the Culver City Arts District. Considering Cog is in expansion mode, it’s a good thing Lim has caffeinated lieutenant Jack Benchakul presiding over the mobile cart inside Good Girl Dinette, Diep Tran’s airy, brick-walled cafe.

For his first signature beverage in Highland Park, Benchakul started the name with A and ended with “ette” to honor the Dinette location.

The Antoinette ($5) is a powerful beverage that includes a velvety smooth two-stage, 48-hour cold brew, which soaks for 24 hours at room temp and 24 hours in fridge “to slow down extraction” and keep it from getting too “wine-y.” A Bulleit Bourbon reduction cooks down for 30 minutes and joins rock sugar syrup. Balance comes from a splash of coconut milk and two shots of Heart Roasters Stereo espresso. Benchakul shakes all of the ingredients with ice before straining the frothy results in a glass.

Benchakul plans to add signature coffee beverages to the line-up as inspiration strikes.
