            Last Saturday, I went to the Phillips' Collection with my friends John and Jill. We went to see an exhibition of Japanese's prints. The Phillips is my favorite museum. I have been at this museum several times last year and I have seen many wonderful exhibits. The exhibition on Saturday was a very interesting exhibition. We all liked it very much. After visiting  the exhibition, we had a delicious lunch at the museum’s cafeteria. We think that we are going to the museum next Saturday to see the exhibition again.

Comment:  It is correct.
