Cho Why, Soi Nana's multi-floored and multi-disciplinary art space, celebrates four years this weekend.

That's four years of exhibitions, documentary screenings, rooftop paella nights and other informal gatherings with arty leaning. 

Back when a group of creative types threw open the doors of a three-story corner shop-house on the fringes of Chinatown in 2014, the "other Soi Nana" was a sleepy row of crumbling buildings—a far cry from the buzzing nightlife hub it is now. 

This Sunday Sep 23, from 2-10pm, they'll be showing off a newly painted rooftop courtesy of Souled Out Studios, who will be occupying the space for the next two months with showcases by Bon, Gong, Alex Face and other names in the street art game. 

Also on the day, there'll be a Chinatown-inspired photo exhibition by Spanish photographer David Terrazas and music by neighboring 23 Bar & Gallery and Belano Kuti. 

Of course, there'll be plenty of food and booze. Chef Jacobo Astray, of Ekkamai's Broken Eggs, will be whipping out Mexican and Spanish food (including his signature seafood paella), while Beervana will be laying on Pabst Blue Ribbon all night at B120 a tallboy.
