My parents are going to be in Dallas for one night only, and it's going to be a Monday night (7/19). They enjoy good coctails and sophisticated cuisine and nicely designed restaurants. Money is no object. They are not too adventurous, and would prefer something Texan, where you locals would go.
I appologise for not researching the board first, but I have limited internet access right now.
Thank you very much for your answers!
