Our family held a Christmas gathering in the Alcove room that is part of the Olives' lounge - actually we spilled out into a portion of the lounge since our group was so big. Since it was Christmas day that wasn't an issue because it was pretty dead at the hotel and in the lounge.
The bartender, Erica, did a great job hosting us and she kept the drinks coming (nice and strong). Same with the next night when we stopped back after dinner elsewhere.
If this review was just based on Erica I would give it five stars but the food was pretty mediocre. I know it was Christmas and it was a hotel bar menu but they really should make a better effort with the quality and preparation of the items they do serve - they were just OK for the price.
Anyway we did not let the food ruin the festivities. Olives worked well as a place for us to celebrate together.
