I have not been to Libby's Manapua Shop for quite awhile. The prices have gone up and the menu on Tripadvisor needs to have its prices updated. That being said, I was pretty disappointed in the food. I tried the Charsui Pork Manapua, Chicken Manapua, Halfmoon, and Pepeyau. The taste and quality didn't do it for me. The fillings on the Halfmoon and Pepeyau were not very tasty and pretty much consisted of bamboo shoots and water chestnuts grounded up.
The manapuas, both charsui and chicken, are better at a lot of other places, including 7-11.
I think people still love going there. Old habits are hard to break.
For me, I will look elsewhere for my manapua fix.
