What will take place on Friday?

M: Everything looks great in here, Vicky. Plus, the menu you’ve arranged looks perfect. It looks like you’re prepared for the grand opening on Friday.
W: The restaurant is nearly ready, but I’m a bit nervous about one thing. I mailed invitations to all the food critics in town, but most have yet to respond. Do you think I should still prepare meals for them?
M: Well, it would be a shame to waste any food. If you’d like, l can make some calls to confirm their attendance for you. I’m free all afternoon and am happy to help.
