Berko, as it's known by locals, is a great place for looking in shops which sell stuff that no-one actually needs.
My favourite shop is
Home and Colonial do a lovely mixture of contemporary, vintage and antique.
Upstairs is more contemporary, shabby chic style
Downstairs is like stepping back in time. Think social history museum where everything is for sale. A delight!
Another favourite of mine is Horsfall & Wright. It's very "Brighton" and I love trawling around the shops in Brighton!
