Interesting choices. I would not pick either the Dallas winner or runner-up for a business dinner myself... a date maybe, but not a business dinner.
Those both reek of the 24-year-old dot.bomb exec hangouts... not somewhere you would take corporate professional types.
As far as Dallas goes, everyone knows that any true business dealings still get done over steak. Trite? Perhaps... but that is just the deal.
Each industry seems to have its own steakhouse of choice... in mine, its Pappas Bros. Dinner any night of the week is a whos-who of various players, former colleagues, and potential clients. Very very interesting happenings going down with some frequency.
