Very very disappointing. The concierge, Pia, recommended this restaurant so gave it a try. Their hostess mixed our reservation up, gave our table away, and the manager said WE caused the confusion, so had to wait 30 minutes. He later admitted their mistake and apologized.
Our table ordered the chef tasting menu...big mistake. Total time in restaurant was more than three hours for a table of 3! And we were only served 3 of 5 courses! At the end, the manager said he would buy us a drink for our troubles...unbelievable. Total cost was $300... Definitely not even close to worth it. Steer clear of Union at Aria.
