I will be spending Shavuos in central Flatbush and would love to daven somewhere with a beautiful, leibedik davening (second day). Also, looking for a nice Neilas Hachag with dancing and singing.
How about BJX which is a kiruv center on Avenue K and East East 29 Street which features a beautifully leibidik davening, filled with singing, warmth and the opportunity to connect with Jews of all ages and backgrounds who want to come closer to Hashem and our Holy Torah.
