Personally I'd go to Viola's. But in general, you're not going to have to look far for a good burrito with green chile in NM.
I, too, as a former Los Alamos resident, immediately thought of Viola’s. I don’t have any idea how many hundreds of Christmas breakfast burritos I’ve enjoyed there. Haven’t been in years since my Dad retired from LANL and moved to ABQ.
True. I like Josie's in Santa Fe, also especially for the huevos rancheros at breakfast, with a side of posole.
