Such a waste. Great little cozy Mexican restaurant for a business lunch that somehow forgot 1) how to make Mexican food and 2) how to cater to larger groups on their lunch break. You will fall in love with its quaint, wooden interior and carafes of salsa, but the love affair will start to wain once you realize how shoddy and unorganized the service is. It's one of those serve tables by committee places where no one will claim responsibility of any table that's out there. As such, you will go through long stretches without key elements for eating your meal and either be ignored or treated rudely when you ask for help. But the real deal-breaker for me in my one (and probably final) trip here was the food. I got a "Carne Asada Taco" platter, which turned out to be a loose definition for what I got. There was a stack of four tiny, over-saturated tortillas with some carne asada on it. No guacamole, no pico, or anything else. Just some carne asada and lettuce on sticky, wet tortillas. Also came with almost tasteless beans and rice on the side. The carne asada itself was really good and some members of my party had slightly better entrees, including the ones who got carne asada burritos which were loaded with guac and such, but we all agreed it wasn't worth the price compared to a trip to Tradiciones, La Tolteca, or even Canasta. Then we got presented with a bill that included an auto-gratuity of almost 30%. We brought it up to the woman who was running the joint for the most part and took our orders and told her to sort that out. She apologizied and said, "Oh, she can put on whatever gratuity she wants." Say what? Who is "she"? You are the only one running the register and taking orders. And how can any server just come up with a gratuity of 30%? Needless to say this place is trying to shakedown large business parties and should be avoided as much as possible.
