By Subway (15 minute walk from the station):
Take E/F/M/R to Forest Hills-71st Av. It is an express stop, and the E and F run express in Queens, so they should be a faster trip from Manhattan. Exit onto the SOUTH side of Queens Blvd, and walk down Continental Ave for 10 blocks; if you are going in the right direction, you will cross Austin St after one block, then pass under the LIRR train tracks. The cross streets are alphabetical; take a right on Kessell St. The church is on the right at the end of the block.
For dinner beforehand, there are plenty of restaurants on Austin St.
By LIRR (12 minute walk from the station):
Take the train to the Forest Hills stop. Exit onto Continental Ave, and head south (into the residential section, away from the shops) for 8 blocks. The cross streets are alphabetical; take a right on Kessell St. The church is on the right at the end of the block.
