Hello Ms. Bailey. This is Andrea Rossi from Amici Restaurant. We are celebrating our 10th anniversary on February 7th, and because you are a regular customer, we are inviting you to enjoy a night of dinner and music. Our anniversary celebration is our way of thanking you for your continued support. As part of this celebratory event, we have also organized a free Italian cooking demonstration for selected guests. And I wanted to let you know that we chose you as one of the participants for this activity. lt will be held on February 9th at 3 P.M. in the function room of Amici.
