The annual culinary and social delight known as the Peninsula Chamber of Commerce “Chamber Chomp”/Taste of Shelter Island will return for its 20th year on Tuesday, April 21 with a little extra bite. The annual gala, an affordable, self-guided gastromical tour to promote the diverse restaurants along Shelter Island, also helps raise money for the chamber and its various community programs. Matt Kalla, Peninsula Chamber of Commerce president, said the event offers an opportunity for neighbors and business owners to interact, but it’s also an opportunity to help promote fine and casual dining at 13 participating Shelter Island establishments. “This really is designed to feature the top restaurants in the local area and to help stimulate business on Shelter Island in these tough economic times,” Kalla said. Kalla said he anticipates a turnout of about 500 hungry residents who, for the price of $15 each, can sample some of the best these various establishments have to offer. Money raised by the event helps the chamber support various community programs, including scholarships for Point Loma High School students and funding the traditional Fourth of July fireworks show, the Point Loma Summer Concerts series and various luncheons and mixers throughout the year. Kalla said he hopes this year’s event will also help raise money for an annual business expo and open house event — possibly in October at Liberty Station — to promote other neighboring merchants. This year’s “Chamber Chomp” is scheduled from 5:30 to 9 p.m., with check-in between 5:30 and 6 p.m. The Peninsula Chamber of Commerce promotes local business and serves Point Loma, Ocean Beach, Shelter Island, Harbor Island, Sports Arena and the Midway area.  Last year, about 500 people attended the restaurant walk — both locals and out-of-town visitors — bringing in about $2,500. The event also highlights local businesses to provide a “win-win situation,” according to chamber officials.  Participating restaurants in the self-guided restaurant tour this year include: • Bali Hai, 2230 Shelter Island Drive; • Old Venice, 2910 Cañon St.; • Red Sails Inn, 2614 Shelter Island Drive; • Kona Kai Café, 1551 Shelter Island Drive; • The Brigantine, 2725 Shelter Island Drive; • Point Break Café, 4865 N.
