I am not sure there is anything better than Lunch 'n Learns and Sunset Seminars from the rooftops of New York City. The power of 'The Big Apple' allows one to organize a networking event with very little advance notice. There are plenty of apps to help to organize Meet Ups - both formal and informal.
When you are having an event in NYC please consider Convene. With locations throughout the city, you can have the most amazing hybrid events all PoweredByZoom.us. And all NYDLA.org members enjoy special pricing at all Convene locations.
See you in the clouds of the city......
