Real Szechuan? No.
Good Americanized Chinese with some szechuan influence? Maybe.
Places like Ching's Table in New Canaan do good Americanized Chinese. Ching's probably has some Szechuan dishes. But if you are looking for that wonderful fresh, lip numbing/tingling sensation you get from real Szechuan cooking, I would be very surprised to hear there's a place in FFC where you'd find it.
I sincerely hope to be proven wrong. But I'm not holding my breath.
Sorry to be the bearer of bad news.
If you go a little further north on the Post road you will reach a real Szechuan jewel called Lao Tse Szaun(sp?) in Orange. The best Szechuan outside of Flushing. Great food.
