Wrong End . Maybee the Townhouse has a franchise on it but the buildings are nowhere near each other.
Heathmans is good and reasonably priced , Exchange is expensive but very good. Particularly an engineer called Nilesh. He's mastered alot of Bjork and Daft Punk stuff. But he is usually booked months in advance.
Transfermation , near Watermans old hitfactory in Borough is also good. Get an engineer called Neil ( as far as I remember ).
