Sol Restaurante Mexicano & Taqueria

Hostess on a Friday night kept us (5) waiting 30 or more minutes, then a part of 7 arrived (no reservation) and within 5 minutes seated before us, so we elected to visit one of the other Mexican res. in Montgomery. How long to train a hostess to make a list of waiting patrons? Will not visit again. La Zona Rosa got our money. I had lunch there previously and that's why the ok rating on service.
