The short answer
Yes, mostly in Gueliz, Hivernage and the Palmeraie. There is Indian at Clay Oven, sushi at HySushi, Lebanese at Babakish and Azar, Greek at Cafe Grec, Italian at Dai, Japanese-Korean at Akira Back, French bistro cooking at Chez Pepone and a Brazilian rodizio at Fuego Latino. The medina stays mostly Moroccan.
In more detail
Gueliz is the international quarter. Clay Oven on Avenue Hassan II runs a tandoor-driven Indian menu of curries and breads baked to order. HySushi does sushi with Thai and other Asian dishes, plus takeaway. Babakish and Azar cook Lebanese and Middle Eastern food, Azar with a nightly live show. Dai is an intimate Italian dining room built around handmade pasta, and Chez Pepone is a French bistro with a changing daily lunch menu.
Hivernage, around the M Avenue development, adds Cafe Grec for moussaka and souvlaki and Akira Back on a hotel rooftop, pairing Japanese technique with Korean flavours. In the Palmeraie, Fuego Latino serves Brazilian rodizio skewers with a dinner show.
Inside the medina, a few places mix styles. M Bacha pairs Moroccan and Asian dishes in an 1896 riad, Mazel Café serves falafel and hummus, and Café Clock is known for Lebanese-style mezze and a camel burger.
International kitchens are useful for fussy young eaters and long trips. Pork and alcohol are more likely on these menus than in Moroccan restaurants, so ask if either matters to you.
