Outdoor dining in the nice parts of America will continue being as amazing as it always has been. NYC is a cramped, overcrowded island that literally doesn't have enough room for dumpsters; trash on the streets, rats, and all the obvious follow-on effects obviously degrade the experience there.
NYC chooses to have rat infested dumpsters and trash bags on the sidewalk, parked cars and traffic.
Other places with NYC density have pedestrian-first areas for outdoor dining, transform car parks into patios in the warmer months, and transform old parking lots into beer gardens, food truck events etc.
