To me, every Mexican restaurant we go to in San Antonio is the same -- adequate but not great.
Los Barrios - decent, but similar quality to the chains of restaurants here
Mi Tierra - :vomit I think that's probably the most overrated place we've ever been
Sausalito's - :vomit The worst Mexican food I've had in San Antonio
La Rosita - same level as Los Barrios
All and all, I think you could go to Alamo Cafe, Chacho's, or Las Palapas and get similar quality as all of those.
The only one that I've ever been to in S.A. that was above average is Guajillo's.
