I'm having my wedding at "John Anthony's on the Water" in Babylon this fall, and I know two other couples getting married there this summer. Give them a call at (631)422-2400...my banquet manager's name is Maryellen.
Their prices were $80 pp April through October and $70 pp Nov through March for a Saturday night wedding...includes cocktail hour, dinner, cake, vallet parking, party coordinater to help plan, patio on the water for pictures, and the place is GORGEOUS! The best thing I liked about it is that the two halls are on different levels, so they're completely seperate...and both face the water! I think my room's max capacity is 240, and we had to garuntee 150...and the room upstairs is a bit larger.
