I saw barnacles at A&G and decided I had to try them. I got to the restaurant, only saw one dish (fiesta del mar) with 'percebes' (barnacles). When ordering, I asked whether we could order them independently, they said yes, but I went ahead and...ordered the whole fiesta del mar. The dish came -- without barnacles. I asked them why there weren't any, and the guy said they didn't have any today. Why would you tell me 30 minutes prior (when I ordered) that you had them and then so blatantly admit to not having any when my food arrives?! Then, the man goes to ask his supervisor about something, then comes back, essentially saying nothing. We waste 15 mins+ doing this which is significant since when I sat down I said I needed to leave after an hour and they said no problem. This means we were 45 minutes into the hour. There is more back and forth between the man and his supervisor, taking up even more time and at this point I don't understand what they are talking about since they keep coming back to add absolutely nothing, only continuing to tell me that they don't have them today. Why are you wasting more of my time to repeat the same thing time after time? There was no service here, it was essentially them telling me that yes, we don't have them, so what? I was frustrated and didn't even know why we were sitting there when we had to go but when I voiced the frustration they had no sympathy. My partner even asked whether the waiter could understand and he looked absolutely appalled that we were frustrated at the situation. The conversation was going absolutely nowhere and he started taking the plates with the food to take back so we got up and left. On our way out, the manager stopped us and asked what happened and when we explained the situation he had no sympathy saying that it was the SEA'S problem that they didn't have them, not their's. I would understand this if it was a daily catch or something, but when you explicitly write out the word PERCEBES on your menu and then I ask and you say that you have them, it's YOUR problem. He was not even mildly apologetic which was an absolute joke. I would never go back here since the service was appalling and had no problem management skills. Food is only part of the experience, terrible service can completely ruin the experience, like mine.More
