Let me say first that I have been to this restaurant before and am not going off one time only experience. With that being said, I would rather have spent my money at Roberto's then Casa Cocina.
To start the meal, it took the hostess a good fifteen minutes to get us a seat in the not busy restaurant. From there we sat at our table for 20 minutes before the waiter meandered over to take our drink order. Before we had our order taken however my friend and I overheard a conversation between two waiters to the affect of "I don't want to have to serve them." Being that we were the only people in the area at the time and the same waiter ended up serving us, there is only one logically table they could have been talking about.
The food itself arrived on time and was well prepared. During that time we noticed that the hostess was at the table next to us flirting with the men sitting there and all the while there was a line piling up at the front of the restaurant. It took another employee telling her that people were waiting for her to start doing her job.
As the meal drove to a close and we waited for the waiter to reappear from the netherland he had disappeared to, my friend and I became impatient and asked the passing hostess for the check. She apologetically went to fetch it while out of nowhere our waiter reappeared and asked if she was getting us the check. We responded with a polite yes and he said "I'll be back in a few minutes to cash that for you." We waiting for about ten minutes before we went up to the hostess to cash the check and leave no tip.
I realize that this accounting is not necessarily a reflection of the restaurant as a whole but I can say without a doubt that it did not seem like any of the other employees were very polite either. We were seated near the kitchen and heard a large amount of grumbling and complaining. I also realize that very few people love there jobs enough not to complain about them, but they should have had common sense and decency not to do it were your patrons can hear.
Needless to say, I will NOT being going back to Casa Cocina again.
