I am trying to host a 30th birthday dinner for a friend for about 15-20 people and would like a private room. It could be anywhere from Oak Cliff to N. Dallas. I would like the food to be pretty good and be around $35/person not including drinks (some place not too upscale and not too casual). I have come up with only 2 places: The Grape (but seems too romantic althoug food's good) or Tillman's Roadhouse (haven't been but heard good things &private room looks great). I would greatly appreaciate any suggestions. Thanks!
