Arto's is located at 307 E 53rd. I've been two or three times (it's my friend's favorite restaurant) and the quality and freshness of the food has been consistent. They make their own pita bread, the yogurt is superb. I've enjoyed the salads, fish and lamb dishes, and the casseroles are quite good. The fried calamari is a good choice too if you like that. The restaurant is moderately priced. The lighting is dim in the way I like it, but it can get noisy. Call ahead to see if they are having one of those private parties. Happy Valentine's Day!
