Whenever I've eaten at Ohana, I always call the restaurant directly, just a couple days before the ADR. While I've never been served by Chef TJ (before he left), I've always had fantastic meals.
The last I was there, I was served pita chips with some tasty baba ganoush and hummus as an appetizer. The entree was similar to meals I've seen by Chef TJ - tofu, veggies, and tempura veggies over rice with some sort of sauce. I forget exactly what the sauce was like, it wasn't really spicy but still very flavorful. There is nothing I didn't like about the dish - everything was flavorful, all the ingredients cooked well (particularly the tofu), and the portion was generous.
Of course, this is in addition to the salad, noodles, broccoli, and bread pudding that's served to the table. The veggie option may vary slightly depending on the chef and the night, but you certainly will not go hungry. Enjoy!
