In order to express the 'immediate future' (I am going to go to the...) in Llanito you would have to follow this method:
The present tense of the verb ' í' ' + i´'
voi í' a la plalla
voi í' al tóïlet
voi í' del dentîta
for the first person (llo) only you can also use 'via'
via í' a la plalla
via í' al tóïlet
via í' del dentîta
