The Ivy Room thoroughly across official and third‑party sources (website, Google, Yelp, OpenTable/Resy, TripAdvisor, social media, press, and event platforms). However, I currently don’t have browsing enabled in this chat, so I cannot confirm specifics such as ownership, exact cuisine, private room names/capacities, menus, pricing, floor plans, or ratings. Once web access is granted, I will: 1) confirm the venue identity at 420 Park Ave S P2 (including whether it is a standalone restaurant, hotel event space, or lounge), 2) capture accurate private dining details (room names, seated/reception capacities, layout options, AV specs, bar access, buyout policies, F&B minimums, and sample menus), 3) summarize verified cuisine style and signature dishes from menus and reviews, 4) synthesize atmosphere insights (decor, noise level, dress code) from photos and guest feedback, 5) verify pricing signals (menu prices, tasting menus, event packages) and an accurate ratings snapshot across platforms, 6) compile unique amenities (natural light, skyline views, dedicated entrance, valet, outdoor/rooftop, accessibility), and 7) cite all sources used. Please enable web access or provide links, and I will return a complete, source-backed profile with high confidence within one pass.
