Fronimo's 3234 E. Speedway Blvd. He makes the sweetest, most delicious onion rings I've had outside my mother's kitchen.
Greek soil is relatively alkaline, so the vegetables have little acidity.
The tomatoes and onions, in particular, were as sweet as nectar. Fronimo's is a mostly Greek fast food restaurant on E. Speedway. But if you don't, you'll recognize them by the long lines of people outside, waiting for their gyro to be sliced to order. Fronimo's serves pretty good gyros, even though they're not roasted on a vertical spit. Other traditional meat dishes are stellar, especially the Athenian roast chicken, bathed in lemon, garlic and oregano, and served with rice or fries, salad and grilled pita.
