The Greek Islands on Halsted street. It very casual with awesome reasonably priced food with beautiful Greek style atmosphere and music. I don't remember if they have outside seating,but it's perfect for a classy date or just with friends. The dress is casual. Try their assorted appetizers as it is the best I ever had.
