May is National Hamburger Month — who knew? Prime sirloin hamburgers, with fries and a soft drink, are only $10 (normally $19) at Wolfgang's Steakhouse in Waikiki's Royal Hawaiian Center through May 31.

It's not National Shrimp Month, but Fumi's Kahuku Shrimp truck at the North Shore has extended its special through May 31: Buy two shrimp plates and get a third one for half off (coupon at www.HonoluluOnTheCheap.com).

Now through Sunday, Starbucks' "however-you-want-it" Frappucinos are half price between 3 and 5 p.m.
