I really enjoyed the 1lb Laulau and Fried rice combo at Kuhio Grill. The biscuits (forget what they are called) that they grill are 'ono too!
The mixed plate at Don's was solid too. Branden Kawazoe hooked us up. Reservation for 20!
For breakfast one morning, we drove up to Waimea to eat at Hawaiian Style Cafe. Drove up to eat the smoked meat and eggs. Get there, they tell us, "We all out of smoked meat!"
My favorite place though, is Ken's. Favorite item is the oxtail stew.
I love Hilo.
