In keeping with its Greek immigrant roots, Chicago West Loop has an excellent selection of authentic Hellenic cuisine. Costa's (340 South Halsted) is reminiscent of a Greek villa, complete with white-washed walls and terracotta tiling. The menu offers a delicious selection of Mediterranean cuisine, including gyros, moussaka, and grilled lamb. Greek Islands (200 South Halsted) is another popular Greek restaurant. Keen to be as authentic as possible, the restaurant imports all its ingredients directly from Greece.
There are also plenty of other excellent West Loop restaurants, and a great selection of authentic cuisines from around the world.
