Glasgow's city centre is a grid of Victorian streets between the Clyde to the south and the M8 motorway to the north. The central area — Buchanan Street, Argyle Street, Sauchiehall Street, and their connecting grid — contains Scotland's largest concentration of Victorian architecture, including some of the finest commercial and civic buildings in Britain. The Merchant City, on the eastern edge of the centre, is the historic trading quarter now home to restaurants, bars, and independent shops. The city centre rewards wandering with your head up: the detailing on these Victorian buildings, and the occasional glimpse of something extraordinary like the Argyle Arcade or the Willow Tea Rooms, makes it one of Europe's more rewarding urban environments.
