first time I have done sth

[engee30]

Hello there,
I'd like somebody to enlighten me:

This is the first time I have eaten snails. - I know that we use the Present Perfect Simple tense in such patterns. But what happens if I write something like this:
This will be the first time I...
a) will have eaten snails.
or
b) have eaten snails.
or maybe something else.

Please help me.

b) sounds more natural to me, but I think a) could be used too.

Thanks again for your concise explanation.

It's wrong to say "This will be the first time I will have eat snails," isn't it?

[MrPedantic]

In standard English, you're right, Daruma: you would need the past participle ("have eaten").

But in some non-standard dialects, no doubt, "eat" might be used.

It's a bit wordy, but not incorrect. You are referring to a situation in the future - perhaps you have seen the menu for a dinner party next week. It will be the first time you will have eaten snails.

I'm planning to go to Paris next month. It'll be the first time I'll have Eiffel Tower.

How does this sound? If it's not good, what would you say?

You're missing the verb - visited/seen/viewed - something else?

[Daruma]

I forgot to put "visited" in my last post.

I'm planning to go to Paris next month. It'll be the first time I'll have visited Eiffel Tower.

How does this sound? If it's not good, what would you say?

It'll be the first time I visit The Eiffel Tower.

This will be the first time I eat snails.
