Ralph's German Bakery, originally founded on the Red Sea coast in Dahab, brings genuine German baking to Road 9 — rye bread, pretzel rolls, strudel, and a full German breakfast that's hard to find anywhere else in Cairo. It has become a long-running expat institution and the standard recommendation for breakfast in Maadi.
Order ahead for bread if you're stocking up; the good loaves sell out by mid-morning.
