Jins or Zoff – location

Hi!

So I have heard great things about getting glasses in Japan. Mostly that it is cheap and quick.

Do you guys have any preferences?

I am terrified of calling, does anyone have experience with contacting them in advance in a way that does not involve a phone call?

And I will be staying in Ikebukuro, on social media I see people visit the stores in Shibuya. Do you guys gave any input store wise or anything.

Thanks in advance,
