How hot is Le Diplomate? So hot that in the middle of a frigid winter when temperatures were in the twenties, diners were taking seats at the sidewalk tables. There were heat lamps, but still. Brunch reservations are especially hard to snag, and it’s been like that since the restaurant opened in April 2013. It looks the part of a Parisian brasserie, right down to the red banquettes, large mirrors, zinc-topped bar, little lace curtains, and windowfront opening to the sidewalk. And it tastes the part, too, with its menu of Gallic staples, from escargots to steak frites to trout amandine to crème brulee. Le Diplomate is big and loud and fun, and though I wouldn’t call it romantic, myself, others obviously do; I’ve noticed lots of couples, including May-December types, and there’s a lot of kissing going on.
