SEA HORSE GRILL,

Sea Horse Grill has long been the optional opening act for musicals at the adjacent Theatre-By-the Sea. The menu plays on the showbiz theme, billing appetizers as Opening Acts and entrees as Main Attractions. We started out with one of the Italian Arias, the pizza della casa ($6.25). With a garlicky marinara sauce and plenty of mozzarella on an especially light crust, it was simple but quite good. Main courses run from the robust "Hen House Special"Ê($14.50), a sauteed chicken breast with mushrooms, artichoke hearts and tomatoes, to a variety of lighter, weight-watching selections. The post-show cabaret menu is more limited, but features some deliciously gooey chocolate desserts.
