bakery 47 in Victoria Road have a barter day, the first Wednesday of the month. I took along some allotment produce. Some chard, leeks, potatoes and home made chutney and came away with two lovely sour dough loaves. 
Just can’t wait to taste my goodies, and I’ll definitely be along for a coffee and cake on one of the days they are open for “real” business. That’s Thur/Fri from 8am and Sat/Sun from 9am. Their website is http://www.bakery47.com
