This place attracts students and tourists that it is easily busy with so-so service and subsequently can lose some charm. But with decent food, it is easy to overlook the unpleasantries of this place.
I've had their chicken kabab and the "Lahem Mischwi" (lamb kabab), and both dishes were tasty with the nicely grilled meat. The sides (fries and salad) were ordinary and nothing to complain about. I'm a fan of their refreshing "Oase-Tee Spezial Sahara" (pomegranate tea with fresh lime, mint, and brown sugar).
Falafel Teller was very delicious. The interiors and ambience are nice as well!
