An culinarily adventuresome group of out-of-town business colleagues are in Philly on business at the end of the month. They've invited me to dinner & I am looking for someplace different to suggest. OOTers always seem to want Italian, but they are open for anything. One has even mentioned dim sum. We are based near 20th & Market, but are fine with cabbing it. Dinner would be on a Wednesday night. Marrakesh was one of the places I thought of. Good? Not so good? I am also open to other suggestions. The only "dislike" noted was curry.
