Westfield High School will be presenting its annual dinner theater on Nov. 15 and 16. Chosen for this year's production is "Once On This Island" by Lynn Ahrens and Stephen Flaherty. This is a tropical/musical setting of Hans Christian Andaersen's fairy tale "The Little Mermaid." There will be a dinner buffet preceding the show each night at 6 p.m., where there will be a variety of entree choices available and the cast members will act as servers. Dinner reservations are available by calling Westfield School at 326-2151. Tickets are also available for the show only and the actual show begins at 7:30 each night. Dinner reservations must be made by Nov. 8. Reservations for show only tickets are not necessary, but encouraged. "Once On This Island" is produced with special arrangement with Music Theater International, New York, NY.
