I've never eaten sushi before or until now

Question

scenario 1: I'm eating sushi.

scenario 2: I'll eat sushi in a couple of minutes.

I say to my friends who sit besides me,

I've never eaten sushi before.

I've never eaten sushi until now.

Do both sentences imply a change that I'm making: I'm eating sushi now or I'll eat sushi very soon?

Answer 1

"I've never eaten sushi before" is the most idiomatic. We would say it in either scenario.

We might say "I've never eaten sushi until now," but in scenario 2 it sounds somewhat unnatural.
