We love Las Banderas. Of course we do not go there to drink, so don't have the same problems as other reviewers. The food has always been outstanding. The staff is very friendly. The owner and wait staff are so sweet to my kids, my kids love to go there. We have been in Valdost for 7 years and this is our hands down favortie place to get Mexican food. The art in the restaurant is done by the owners brother and yes it is different, but is is also cool to look at.
I am not sure about good atmosphere, because tables are too close to each other, so you can hear peoples conersations. Crazy pictures that probably made by 4 years old kid are everywhere, even in the restrooms. And don't order house drinks. For your safety :) I saw the stuff they use for margaritas. Shots are extremly small. Probably like half of a normal shot. All this together made me feel that I don't want to come back there.
I have been there many times because the people I hang out with eat there. however, i have been to many mexican restaurants and this one is the worst. try another one in valdosta long before trying this one. unless of course all you wanna do there is drink. they have good prices on drinks but the food is not mexican food.
