Locally, I visited the newish location of Trevino's in China Spring. It is a nice spot and still a reliable choice in Mexican food. I liked their food when they were in the Hewitt area. I seemed even a little better in this location. Good enchiladas and fajitas. Give it a try.
Mi Tequila on Valley Mills was a no frills lunch spot that offered a limited menu, quick service, and cheap prices. As a lunch stop, it is OK if you are hungry or in the area. It won't crack my top five but it will do for lunch.
