How's everything going?
I heard you're going to be in town next weekend.
It's been a really long time since we had a good catch up.
Let's meet up and go for a drink or dinner.
I know a great little Italian restaurant on Downtown Avenue, which is literally a stone's throw away from my office building and not too far away from my apartment.
Shall I make reservations for 8pm?
Text me back or send me an email.
It would be really great to show you around Chicago, as I know you've not been here before.
There's lot to see and I would love to show you around.
See you soon!
