I was told after the service, a group goes to the Fuddrucker's Restaurant, which isn't far from the church. If you would like to learn more, check out this website:
FROM THE CHURCH'S WEBSITE:
Praise is a natural response to God in all His perfection. As we grow closer with God, getting to know and experience Him, ordinary moments can become special occasions for grace to work in us. We can see God's love for us revealed in His creation. As an example, St. Alphonsus Liguori told of St. Mary Magdalene of Pazzi (http://en.wikisource.org/wiki/The_Practice_of_the_Love_of_Jesus_Christ) and how, "when she held any beautiful flower in her hand, was enkindled by the sight of it with love to God; and she would say: 'And God, then, has thought from all eternity of creating this flower for love of me!' Thus did that flower become, as it were, a dart of love, which sweetly wounded her, and united her more and more to her God."
Our personal experience of God's love changes us. Even our view of the world changes and we can see it filled with God's presence which in turn makes us thankful. This is the proper attitude of creatures to their loving Creator. As the priest says during the Mass, "Let us give thanks to the Lord our God," the people respond, "It is right to give Him thanks and praise." Often charismatic gatherings spend time singing songs of praise.
St. John of the Cross explains that when living in close union with God, which is a result of Baptism in the Holy Spirit, "a soul always walks in festivity, inwardly and outwardly, and it frequently bears on its spiritual tongue a new song of great jubilation in God, a song always new, enfolded in a gladness and love arising from the knowledge that the soul has of its happy state." He also teaches that a life of joy and praise is normative for souls in close union with God, saying, "there is no need to be amazed that the soul so frequently walks amid this joy, jubilance, fruition, and praise of God." (St. John of the Cross, The Living Flame of Love, stanza 2, paragraph 36).
