Sonic Hawaiʻi Kapolei is Oʻahu’s first Sonic and the second in the state, after Kahului on Maui opened in 2023. The locally owned drive-in opened on May 16 at 5001 Kapolei Parkway. It has five drive-in stalls with carhops on roller skates, a double drive-thru and patio seating. Hours are daily from 7 a.m. to 2 a.m.
The Kapolei menu includes Hawaiʻi-only items. The teriyaki smasher, developed with Aloha Shoyu, launched when the drive-in opened: two Angus beef patties with cheese, teriyaki mayo, Aloha Shoyu Da Yaki sauce, lettuce, tomato and onion. Starting Monday, Nov. 16, Sonic Hawaiʻi is adding an ube coconut slush float for $5.99, sold all day at the Kapolei and Maui locations. Condensed milk lines the cup, then ube and coconut slush, Sonic’s soft serve, and more condensed milk on top. Any slush on the menu can also be turned into a float. On launch day, the first 40 customers to order the new float will get Sonic stuffies; the story does not say whether that is 40 per store.
