What to say to this: “that’s good, mine was pretty good, I had a training day and me and some other coworkers ate together” should I say “that’s cool” or something else?

Did you go somewhere to eat? Where did you go to eat. What did you eat? What fid you all talk about. Was it fun? Who all was there? Anything interesting happen?

That’s cool is good.
