Best evening walk in Chennai?
Public, well lit, an hour or so. I'd rather walk than sit across a table the first time.
Meet in daylight the first time. Everything else can follow.
If they can't do a short call first, that tells you something.
The promenade, an hour before sunset. Easy to walk and talk.
Don't push through. Say it was nice, finish your coffee, go home.
Book something with an end: a gallery that closes at six, a class that finishes.
