On Sunday nights, Pupusa Mami, a one-woman pupusa pop-up, offers sustenance to the Lonestar-drenched folks of the dive bar Lil' Danny Speedo’s Go Fly A Kite Lounge in the East End. Filled with beans, cheese, and meat of your choice, every pupusa is made by hand on the patio. You can also snack on scalding fried plantains served, refried beans, mountains of vinegary curtido, and spicy salsa. But be warned: the pupusas are third-degree-burn hot when they arrive, so just chill out and know your cheese pull is coming.
