This restaurant is a no frills place located conveniently next to the Hilo Farmers Market. The House Special Seafood Curry is very flavorful & “a must try” item. Each spoonful is filled with assorted seafood; shrimp, calamari, fish & a few scallop, as well as...More

Just as good as it was two years ago. Very basic place with very good food at very reasonable prices, especially daily specials.

We were trying to go to nearby "Pineapples" but it was ridiculously packed with haoles, like they came off the cruise ship. We decided to walk in this strangely empty Thai place but it was near where we had parked our car. I am glad...More
