Critiques have called it a must for international foodies, Olsen´s address in Palermo Hollywood is B.A.´s culinary capital and the restaurant itself has a warm inviting glow and oozes style, so how could it go so wrong? The food was perfectly good but it certainly didn´t blow our minds away. Service was poor and bordered on arrogant at times. Without a booking don´t expect a good table, no surprises there but prepare yourself for not being shown to your table. Our aperitifs took ages and we were still drinking them when our starters arrived. Our main problem, however, occured when we only had a Mastercard in a Visa only restaurant. Having not been warned about this, we were genuinely surprised at their limited flexibility but were then angered by their reaction to the situation. It ruined the meal and I would certainly not recommend it at all. Trust was clearly an issue for them and we were made to feel like fraudsters who had done it on purpose. They begrudgingly agreed for us to return the next day to pay having dismissed the idea of one of us popping to an ATM. A renowned restaurant should be a joy to experience and leave you loyally passing on recommendations at the first opportunity, in this case Olsen failed massively.
