I'm surprised it wasn't at LANL, considering one of the shops in Los Alamos near the lab has this amazing hatch chile burrito that's under $8 and is 10/10 in terms of flavor.
e.g. Vick's Vittles, Tia Betty Blues, Golden Pride, and of course the old standby Grandma's K & I Diner which has been feeding nuclear engineers for 62 years.
