I suggest Del Posto. Best pasta in the city (perfectly sauced and served hot) and excellent service. I took family, grandparents and kids (10 &12) and we were seated upstairs in a seculded area. Yes there is the white tablecloth but wait staff is gracious and both attentive and good natured without being overbearing. Great conversation, food and wine - a memorable evening. As to the others -- WD 50 would be a bit loud for group conversation -- although plenty to talk about as food on plate is as much a conversation piece as food itself. I haven't been to ABC but I've never been to a Jean-Georges restaurant that I didn't like.
