WEIGHTY MATTERS: Singer-comedian Frank DeLima, who makes his Hawaii Opera Theatre debut tomorrow night in "The Pirates of Penzance" at Blaisdell Concert Hall, is still trying to slim down. He's far from svelte, but he's dipped from 320 to 245 pounds, and is hoping to melt away another 45. "I promised the kids at 'Aina Haina school that I was going to fit that XL shirt they gave me last year," he said. "I've already worked down to the XXL shirt that the students at Kalama School on Maui gave me, when I was XXXL, and the fifth- and sixth-graders thought that was a hoot."

ITEMIZATIONS: Pals of actor Welly Yang, whose theater company, Second Generation, earlier performed here, may be happy to hear that he's engaged to co-star Dina Morishita.

IATSE, the trade union, is convening this week at the Sheraton Waikiki and Royal Hawaiian hotels, with delegates from 13 districts in attendance.

NOTABLES: After two days at the recent Hotel & Restaurant Expo at Blaisdell Center, where he tended to his Clipper Mill and breadbaskets.com booth, San Francisco-based Bob Carrigan enjoyed an exquisite dinner at Shanghai Bistro, having met owner Li May Tang at the exposition. Carrigan globe-hops to all major restaurant shows, including Shanghai, so he had lots to talk about as he enjoyed Chef Chang's dim sum and specialty martinis before meeting friends for dinner. Shanghai Bistro serves up some of the tastiest and prettiest morsels, a feast for both eyes and tummy; if you have a birthday, order up an exotic "sculpture" of sweet pastries, shaped like fishes or dragons. ...

Retired physician Garrett Saikley had a surprise birthday hosted by partner Bobby Carpenter Sunday night at Le Bistro, but as soon as the guests settled down, the power went out. The restaurant didn't skip a beat; tables were moved to the Niu Valley Shopping Center parking lot, where the meal al fresco 'neath the stars made it only that much more memorable. Entertainers Cathy Foy and Guy Merola, backed by Alethea Train, provided music by flashlight. Ah, glow biz. ...
