My preferred meeting location is around Hudson Yards, or anywhere within a few miles of Chelsea. Feel free to pick a place that is convenient for you, or we can just go to the Blue Bottle Coffee in Hudson Yards mall (20 Hudson Yards #228, New York, NY 10018). There is a lot of public seating in the mall. The time slot says 1 hour but I will generally have up to 2 hours available for a coffee meeting. Details: https://cal.com/jameschang/coffee.md
