If you're staying at The Conrad Hotel, Brookfield Place is right next door and has tons of restaurants for brunch/lunch/dinner (Sant Ambroeus, PJ Clarke's, Anassa Taverna, Parm, Black Seed Bagel, Le District). It's also beautiful to walk along the water nearby.
Raoul's is one of our all-time favorite spots in NYC! Walk in for a martini at the bar, french fries (ask for their famous au poivre sauce on the side), and the banana bread pudding for dessert. Make sure to say hello to Eddie (the manager in the bowtie) and tell him you're in town for our wedding!
