When we travel, we know that anything in the Hilton/Hampton family is probably going to be great.
My suggestion is to stay at the Hampton Inn & Suites SouthPark at Phillips Place - This is near some nice restaurants like Cheesecake Factory, Maggianos, PF Changs, McCormick and Shmicks, Ruth Chris, etc.

You could also try Courtyard Marriott - This is near Miro, 151 Main, Jo Jo's China Bistro, etc.
