In general restaurants are not healthy, but sashimi, poke, salads without heavy dressing, and raw vegan items are all healthy. Thai food without rice, like an eggplant and chicken stir fry, is pretty healthy outside of the salt. Hawaiian can be healthy too if you skip the rice and mac salad and get just fish beef and chicken.
Foodiedom crept up on me gradually. Now I have 12 different types of vinegar. Partly this is from adopting a better diet, since it is more of a challenge to have delicious healthy food.
