IIRC the cost of the actual Chasuna night I heard is $1,200.
Paper goods instead of real dishes, buffet style food, “DJ” music, and family and friends chipping in by making potato kugel etc. with students clearing up. And I assume the shul is free.
I believe they’re up to Chasuna number 5. Only R’ Yoely Roth’s Bresolver Chasidim so far. So whoever wants to sign up either join them or simply call up R’ Roth to see if he accepts outsiders. And get some folks to help you with the kugel…
