There's also several markets around this area on a Sunday, you could start off with Petticoat Lane early on, then move on to Spitalfields market. Then there's Brick Lane market, quite different to Spitalfields, plus some record shops, vintage clothes shops, another covered market and loads of food stalls around Dray Walk and the area at the top of it. Dray Walk is off Brick Lane. And of course if she likes curry you're spoiled for choice (as a change from Lordship Lane :) ) Easyish to get to the area from ED, 35 from Camberwell Green goes to Liverpool Street station and it's all a short walk from there, alternatively a 40 to Aldgate.
