At this time, there is insufficient verified public information to confirm that HiSquare Inc., located at 894 6th Ave FL2 in Midtown Manhattan, operates as a restaurant with on-premise private dining rooms. Available references identify HiSquare as an event-focused business, suggesting it may function as an event management or venue-booking company rather than a dine-in establishment. No confirmed details about an on-site kitchen, culinary program, menu, beverage service, or designated private dining rooms at this address are available in the data accessible to me. As such, specific information on room names, capacities, audiovisual setups, floor plans, food-and-beverage minimums, or buyout options cannot be reliably provided. If HiSquare Inc. does facilitate private dining, it may do so by coordinating events at partner venues rather than hosting on its own premises. For planners seeking private dining in Midtown, typical offerings in comparable settings include intimate rooms for 8–20 guests suited for boardroom-style meetings, larger salons for 30–60 guests with flexible seating for plated dinners or cocktail receptions, and full buyouts for 80–150 depending on venue layout—often accompanied by integrated AV, dedicated event coordinators, curated prix-fixe menus, and bar packages. However, these are examples of common Midtown private dining capabilities and should not be assumed to apply to HiSquare Inc. without confirmation. To obtain accurate, venue-specific details, please contact the business directly using the phone number or website provided by the requester, and request current documentation (room capacities, menus, minimums, AV lists, and booking terms).
