"Great Mexican restaurant in downtown Sunnyvale serving authentic Mexican cuisine but what really stands out are the drinks. The margaritas are authentic, delicious, and unique. Plenty of outdoor seating on Castro Street. [The Food] The food here is great for a Mexican restaurant. Competition is tough in the Bay Area, but I would give them a 8/10 for the food. It tastes real, but a little lacking in uniqueness and flavor. However, still very good. The prices are fair for the Bay Area. [The Drinks] We frequently come here just for the drinks. They have Margaritas that don't taste watered down or artificial with a ton of sugar. I feel like they use real fruit, good tequila, and put care into their recipes. We were really impressed. They have these spicy margaritas which are amazing. One of them, they roast the Jalapeno's beforehand giving the drink a smoky flavor. The Guava Margarita is probably their best drink. Definitely worth stopping by and getting drunk here! [The Location] Location here is right on Castro Street in downtown Mountain View, near the train station. They have lots of outdoor seating, restrooms available for customers, and fast service. I never felt like I was too close to anyone, and the sunshine was really nice. Overall, a good Mexican restaurant with an amazing bar. Probably the best margaritas in the South Bay. Worth a visit."
