My family will be in NYC over the Christmas holidays. I have tried to make reservations for Christmas Eve dinner and lunch on Christmas Day, but most restaurants we have tried will be closed. We do have reservations on the 24th at River Cafe, but our lunch plans on Christmas Day are at Tavern on the Green. Any other suggestions? I understand that Tavern has mediocre food and slow service. There will be 7 of us. We would like a special, memorable meal.
