We go here frequently. The place is clean, the food is good, the service is attentive, and the prices are completely reasonable. The servers always make you feel welcome. They're always willing to explain something we don't understand. The outside of the place looks kind of "corporate," but on the inside you'll find Vienna neighborhoods represented all around. From the residents to the office workers, this is a "home town" place. I'm surprised by the couple of poor reviews--we've been coming here for years and our food has *never* been cold. Or slow. Or bad. The chips are always warm, and the red salsa is our favorite. (In fact, we've started ordering an extra 12 oz carryout of salsa to take home with us.)
The portions are large, the enchiladas and refried beans are nicely done. The chile rellenos are the best in the area. And the molcajete is amazing. Although we have some go-to favorites, we frequently try something new and we've never been disappointed. (And I know I'm dwelling on this, but we've never *once* had bad food come out of this kitchen. And honestly, I can't say the same for *several* other Mexican restaurants in the area--where we *have* gotten bad food.)
Don't get me wrong. I wouldn't put Tequila Grande in the same class with the best Mexican places in, say, San Antonio (that's a whole different food group). But in the Northern Virginia area, and certainly in Vienna, Tequila Grande is clearly the best around. The fact that it's a family-owned place, and not part of a chain, or a chain wannabe, is an extra plus in my book.
Yup, we'll be back.
Hope this helps!
