Can you correct this Japanese sentence? ?

Question

ashita tomodachi to issho omise ni itte mo ii desu ka?

would that be correct or do i need a "ni" after issho? or is it optional?

Answer 1

ashita tomodachi to issho NI omise E/NI itte mo ii desu ka?

you need 'ni' after 'issho'.

but second 'ni' can change to 'e'.

'omise e ittemo iidesu ka?' is more mature japanese. but we say 'omise ni' even there're 2 'ni' in one sentence. though its gonna be daily conv.

Answer 2

I'm not 100% sure but maybe

ashita tomodachi to issho ni omise e itte mo ii desu ka.

(I think mise needs へ - directional particle and I always use ni after issho because that's how I learned it but it might well be optional.)
