The enchiladas and chile rellenos burst with authentic flavor, complemented perfectly by fresh, homemade chips and salsa that set the tone for a warm, family-run atmosphere. Generous portions like the massive super burrito and flavorful arroz con pollo made every visit memorable, while the friendly service and cozy ambiance made me feel truly welcome.

The enchiladas and chile rellenos were fantastic, and I loved the family vibe; everyone treats you like one of their own. The homemade chips and salsa were super fresh, and the super burrito was gigantic-definitely meant for two people to share. Even though the service was a bit slow, it was friendly, and the food was so good that I can't wait to come back again!

Food was not good. It tasted very dry and old.
