Japanese: One of the oldest Japanese restaurants in Chicago, Itto Sushi caters to both Japanese and non-Japenese patrons (its website can be read either in Japanese or English). It's an izakaya which is a type of Japanese drinking establishment which also serves food to accompany the drinks. The menu is designed for sharing (like Spanish tapas) so be adventurous and try several of the small dishes. If you like them, order more. The atmosphere is low-key and guests are encouraged to sit back, enjoy your meal with some good drinks and friends. Its beer selection is great but leave room for sake or shochu (a low proof distilled alcohol from Japan).
Sushi: Fresh sushi is the name of the game at this Lincoln Park Japanese favorite. You can choose a seat at the counter near the front of the restaurant or a table near the back where it's a bit quieter. The tuna rolls or the chef's specialty rolls are sure to satisfy your raw fish craving.
