apushata,
On another thread you mention you live in Brooklyn. If you work in commuting distance from there, what restaurant can you enter or leave without being seen by a Jew, with certainty? This is NY Metro.
Also, I’m wondering, even if you would not be seen, does Maris Eyin allow it? The distinction of Maris Eyin seems to make no difference even if it were to occur in Saudia Arabia with not a Jew within hundreds of miles, any more or less than on 13th Avenue in Boro Park. Cherrybim also made note of this point above.
