In checking the archives and from the people who wrote (many thanks), I
learned that Buenos Aires is complicated. Apparently, there can be flour
in spices, so people recommend ordering things plain. Some had very good
experiences; others were more concerned. There are stores that sell
gluten-free food, especially a chain called dietetica.
A couple of restaurants recommended no longer exist.
Thanks to all.
