In the early evening, most of the eating places are very busy. Bars are by far more popular. Although the Market Square sign says that it closes at 8pm, but by around 6pm, most shops are already closed.
Below are some of the pictures I took of the ByWard Market in the evening. All pictures were taken with 5D & EF 35mm f1.4L hand held. Click on the picture to see larger version.
