Fadi's is a cafeteria-style restaurant specialising in Arab food. You pick your menu item and then choose your veggies and dips, pay, and have a seat while you wait for your meat to cook. You also get a basket to fill with however much bread you want.
The restaurant is one of the few I really like for its interior designs; it has a nice tan-golden color scheme and an arch motif along the walls, and the Dallas location has chandeliers hanging from the ceiling. It's a casual atmosphere though.
Fadi's has also been named one of the best options for veggie dining in Dallas, and their Vegetarian Platter proves it, with large variety of sumptuous greens and hummus to try, all on one plate.
