Some dates call for a perfectly stirred martini, and those dates should be saved for dinner at The Greenhouse. While the Jefferson Hotel is popular with foreign dignitaries—some of whom might be eating at the table next to yours—the candlelight, historic fireplace, and tables cordoned off with curtains inspire more romance than business. Regardless of your reason for being here, you’ll want to dress up—your best blazer would fit in well. The menu is mostly fancy classics like scallops, oysters, and squid ink risotto, and while nothing’s revolutionary, everything is prepared exceptionally, and the white tablecloth, classic DC vibe justify the price tag.
