On days like today, i like to walk from Penn to my office near Union Square. The walk would be much better with a really good iced coffee. Where's best place to stop at halfway point? Say near Madison Square Park. I tried Eataly - blech - way too watery. Need it to be actual iced coffee, not iced coffee water like too many places serve. As a benchmark, I like the Mud Truck and Orens is ok as well. No DD or Starbucks of course.
