Why did the woman change the restaurant for dinner at first?

M:Have you decided where to take the client to dinner tonight?
W:Well, I originally made a reservation at Apple’s, which is a steakhouse and then I found out that the client is a vegetarian. I then tried to get us into a private room at Anna’s Garden, because the main dining room is too noisy, but now the rooms were all reserved. I got reservations at Move, though, for 7:30. I haven’ t tried it, but I heard it was good.
M:Oh, I’ ve been there. The food is excellent. It’s right next to that Japanese place, Tami, where we had Joan’s birthday party last month.
W:Right, traffic can be heavy going that way. Let’s wrap up the meeting by 6:00 so we will be able to arrive there before the client.
