the diet guru

I downloaded megaman starforce zerker x ninja and I´m doing my best to do every sidequest I can do to get the strongest megaman ever, anyway, I acepted a sidequest for a fat girl in the suite or grizly pike hotel, she asked me to find the diet guru which it´s supposed to be on the city but I ca´t find it :'(, does anyone knows where it is?
