Got the green curry. Since when is rice an additional option with curries? The dish had more chicken than usual but the curry was the thinnest I've ever had. Place is a bit more tattered than the pictures show.

This restaurant changed their name to Hilo Siam about 3 years ago. Delicious food. Have been going there for years. Only reason I gave them a 4 is because some of the booth seats need to be reupolstered. Location is conveniently adjacent to the Hilo outdoor markets.

We were hoping to eat some good Thai food. We were really disappointed. We ordered soup, spring rolls, pad thai, fish curry, and chicken cashew stir fry. It was horrible and inedible. Not the cleanest place either.

Not pretty, not polished servers--but absolutely the BEST Thai food anywhere. The green curry is beyond incredible. The red curry is amazing. You cannot go wrong with any menu item. The prices are reasonable. If you're going for the ambiance, go somewhere else. If you're going for the best Thai food, no need to look elsewhere--this is superbly delicious!

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 we did because the plates of thai food that we got where simply awesome, we... More

There was no one in when we walked in early evening so wasn't too sure about the place. Wide choice on the menu and I had delicious tempura chicken for my main with rice and spring rolls on the side. Big portions, reasonable prices and tasty. Just could do with a bit more ambiance. Strangely, they didn't have satay chicken... More

Like most Thai places the decor is well...serviceable. The food was great! From the fresh shrimp rolls to the shrimp satay or the Pad See Ew, the Green Curry Chicken and the Pad Thai were all great! Very reasonably priced. Our family of 6 feasted for $80.

Our family of 5 had a delicious dinner here for about $70US. Excellent service, very flavourful, and large portions (took home a few doggie bags). Nothing fancy, but good thai food!
