Revenues rose to £10.56m from £9.19m.Tasty operates six DimTs and eight Wildwoods. The restaurants operate in London and the southeast. Tasty has just exchanged contracts for a new unit in London's Canary Wharf, expected to be opened next month.Last week, Tasty's much bigger peer Prezzo, the Italian restaurant chain, posted a sharp rise in profits and also said trading remains strong.Shares in Tasty jumped more than 5% after today's announcement.RG
