We are looking for a venue in the Southlake TX area for a wedding rehearsal dinner for 75 people. Open to steak, Italian, or Mexican. With many out of town guests, we would like to be with in a 5-10 minute drive of Southlake/Colleyville.

Not sure if their private rooms are quite large enough, but have seen private parties there.
The food is good, a varied menu.

Thanks Joy_ed. I will inquire about their accommodations.

Patrizio's Osteria is practically built just for wedding receptions and rehearsal dinners!

Not sure how soon the event is, but Del Friscos Grille is currently under construction, too. It's supposed to open in the spring.

Try the Copeland's restaurant in the Hilton Southlake.

Several years ago I attended a wedding rehearsal dinner at Old Hickory Steakhouse in the Gaylord Texan in Grapevine before it was bought by Marriott. It was held in a private room in the back of the restaurant. There were about 75 people that attended and it was a very nice atmosphere with good food. Of course, I don't know how it would be now that Marriott has taken over.
