One of my favorite weekend activities is taking the redline down to Chicago's Chinatown and spend the afternoon exploring new places.
Start by going to one of the numerous dim sum places for one of the best and cheapest meals in the city. My favorite is Phoenix. It can have a long line and be a little hectic but definitely worth it. Get the steamed buns and peking duck.
After lunch stop by and get a bubble tea or a lychee frozen drink at one of the numerous places across the street in Chinatown Square.
