Situated on the 43rd floor of the ExxonMobile building, the floor-to-ceiling glass walls encasing the Petroleum Club offer breathtaking views of downtown which make you feel as if you’re floating above the city. Up-tempo dancing and dinner is a big deal here and the dress code of jacket and tie is taken seriously—in the mid-'60s, legendary arts patron John de Menil caused a minor scandal by showing up in a Nehru jacket. What began in 1946 as an exclusive club of and for gentlemen (even the wives of the most powerful members could not dine in the “men’s grill” and were relegated to the dining room only) is now more democratic with membership open to all and highly comprised of those who make their fortunes in the oil industry. The steaks here are among the best in town and everyone tries to save room for the pecan balls (orbs of vanilla ice cream rolled in chopped nuts and bathed in homemade chocolate sauce). It’s a little bit retro—think Dynasty or Dallas without the big shoulder pads and big hair. But as far as big jewels are concerned . . . well that’s another matter.
