DO NOT use for special events!.
Carrabba's has subpar service on a normal night, but using them for our Rehearsal Dinner was a huge mistake. THEY screwed up our reservation. We reserved their outdoor room months in advance, giving them a credit card number so that they would reserve the entire room for our party exclusively. When we arrived, they were still seating people in our private party area. We spoke to the manager that evening (Nigel) asking him to stop seating people in our room. He continued to seat people in our area, explaining that Carrabba's hadn't run the aforementioned credit card, so there was no downpayment for the entire room. This is obviously Carrabba's fault and this manager should have taken steps to rectify the situation. Instead he was unacceptably rude to my family and friends.
If that weren't enough, the service was unbelievably slow - we were ordering from a set menu and still were not served for two hours. Our drinks were not refilled for the first two hours we were seated as well. We had to ask them to bring out the cakes we'd dropped off earlier, which were supposed to be displayed on our arrival.
I wouldn't recommend coming here on a normal night - the service is slow, the food is only so-so, you'd have better luck at Macaroni Grill or the Olive Garden for the same price. But NEVER use them for special events. They lack the managerial experience and professionalism to handle it.
