The East Side King pop-up at Toki Underground

By Lavanya Ramanathan

For just one day, Paul Qui and Moto Utsunomiya of Austin's East Side King food trucks have uprooted from their usual perch on some of Austin's streets to serve a handful of mint-and jalapeno-covered treasures atToki Underground.

Why the pairing? Qui (of "Top Chef" and Austin restaurants Uchiko and, now, Qui) is in town to take part in this weekend's charity foodie marathon, Sips & Suppers.

The ESK pop-up opened at 11:30 a.m. today, and if you're familiar with Toki, you'll be comforted by the fact that the organized mayhem of loitering in the narrow stairway, leaving your name and getting a text when your seats are ready remains the same.

Once you're seated, you're handed a fancy embossed postcard of a menu that boasts six dishes ESK regularly serves on the Drag, South Lamar and other Austin streets. Prices range from $6 for a garlicky vegetarian Liberty Rice bowl, to $9 for Thai Chicken Kara-Age, the increasingly ubiquitous rustic fried-chicken dish.
