The pulse of this retail mecca is unmatched anywhere else in the city. Here, ritzy enclaves of townhomes are interspersed among luxe residential high rises and commercial skyscrapers that jut up alongside the Water Wall, one of Houston’s only real “tourist destinations.” Big-spending businessmen convene over power lunches along Steakhouse Row. And ladies who lunch can be found toting their LVs on the tree-level terrace at Up in Highland Village.
