Have you tasted one? Normally for those who live in Manila and maybe bulacan areas, goto refers to lugaw with lamang loob. I just went to Laguna last week and we ordered one and I was surprised na their goto is like papaitan and it tastes like one. Yup no rice or lugaw at all, just plain lamang loob in thick oily soup. The manang said na ganun daw talaga ang goto sa laguna and batangas. It tasted good naman, lasa ngang papaitan. Pero I think hindi sya like goto sa atin na you can eat on its own but more on ulam sya or pulutan.
