4. Bond at The Langham Hotel
There's a reason this place looks like a million bucks, it used to be a bank for the Federal Reserve. We suggest you deposit yourself and a date here to discuss figures — hers, namely — over a plate of speck carpaccio and a couple of Business Casuals (Hennessey VSOP, blackberry brandy, fresh lemon juice, and champagne float). Worth the investment every time.
