McDonald's has lost a legal battle in Europe over the 'Big Mac' trademark. The battle centers around the Irish fast food chain Supermac's, with McDonald's claiming the name is too similar to the Big Mac and would confuse customers. But the EU Court ruled that the Big Mac trademark does not apply to any other food categories other than burgers. Supermac's managing director Pat McDonagh accused McDonald's of employing "bullying" tactics to "stifle competition". McDonald's will still be able to sell its iconic Big Mac under the name.  Supermac's offers an identical burger under the name 'Mighty Mac'. What's your all-time favorite fast food sandwich?
