Has Yo! sushi (as opposed to Yosushi! which would be sushi by Yahoo) done the right thing by adding the tag line "more than sushi"? They're coming on 12 years old now and maybe have hit the wall in growth terms ... but do those extra words pull in additional passing traffic? People looking for sushi and pizza? Folks with partners who don't do raw fish and are hoping for a bit of steak?
Next up, "Apple ... more than fruit", "McDonalds ... more than burgers", "Pizza Hut ... what is says on the tin"?
