Does anyone know any good restaurants in dallas texas (highlandpark area) with private room for 8 people?

my fiance and i will be eloping sometime next year. the wedding will fall on a thursday at 2, we want to go eat somewhere at 4 with the family, its a total of 8. we want a cute restaurant nice enough for us to show up in our fancy gear but nothing that will cost us too much, 50 dollars per person or so. we won't go all out is just something to do with our rents and two best friends and then off to spend our time together. any suggestions?
