We just went to Casa Bonita in a group of 5 to celebrate my high school graduation. It was absolutely the worst service we've ever had anywhere. I'm not normally one to complain because I work at a restaurant so I know things happen, but this time I can't even try to come to their defense. We walked in around 7:30, we waited 10 minutes before anyone even looked at our table, let alone take our drink orders. It wasn't busy. There were maybe 12 tables sat so it wasn't like they were overly busy. It shouldn't have been hard to grab us drinks and bring us chips and salsa. Eventually someone who was supposed to be off grabbed our drinks because we were already looking upset and said he'd make sure our server would be there soon. She finally comes over and asks for our drink order and when we say a guy has already taken the order and proceeds to call him "such a dork" when in reality he was trying to save her butt. Then we get our drinks but chips and salsa are still not out and nobody has been by to take our order. When she FINALLY comes back to our table (and just to intensify our frustration, she was sitting at the bar 5 feet away talking with two other waiters and playing on her phone) she takes our order. We never saw her at our table again. Just watched her sit back at the bar, continuing to chat and play on her phone. We are visibly upset, especially when we start receiving dirty looks from other waitresses and then notice the owner ALSO sitting at the bar just playing on his phone. We're sitting there, looking around and another waitress notices and asks if she can get us anything to which my mom replies "food, drinks, anything really". We watch her go over to the owner who immediately goes back on his phone. Never in my 2 years working at a restaurant has a guest complained and my manager didn't immediately go over to there table to discuss the issue. Finally, we're so upset and hungry that we just decide to leave. In every similar situation we've ever been in, we usually still pay for the drinks we've had at least, but not today. The owner sees us leaving and jumps in front of us. My mom says "just cancel our order we're going we've been waiting way too long" and he immediately gets defensive saying how busy everyone is and saying he's been stuck in the back for awhile now. Clearly not. We watched him and three of his servers sit at the bar for the last hour. He begs us to come back in saying "come on you came to celebrate your graduation please be my guest". Absolutely not. We waited too long and then he lied right to our faces. Honestly, the worst part was that he was arguing with us in front of the restaurant , begging us to stay, while trying to contradict every complaint we had. It was just disrespectful and makes me never want to return to my favorite restaurant.
