The grand opening for La Roca was just yesterday. I ate there twice before then. The first night was a little chaotic. The service was a little slow because the restaurant was crowded and the staff was new. It was a soft opening and the owner received comments and suggestions from patrons. When I went back the second time, they had the kinks ironed out and took my suggestions seriously. The service was better and the food was better. It's a nice place. I went with a party of 10 and everyone liked their food. The service was great. I know what you're talking about with the margaritas. Everyone at our table ordered one. Our waitress explained the differences in them, again, the learning curve of a soft opening. A visit to La Roca would not be a waste of time or money. If you don't give it a try, you'll be missing out.
