There are some good independent shops in Teignmouth including 'Turn of the Tide' (art), 'hub' (gifts and household luxury items), 'Celeste' (ladies' fashions). The local supermarket is the Co-op in Teignmouth but there is a large Tesco, ASDA and Sainsburys in Newton Abbot if you would prefer more choice.
Muse played live in Teignmouth in 2009, an event televised by the BBC. Absolutely fantastic.
Not quite Muse but some great local bands that play live every year. When they are not supporting Muse that is.
