How do I get there by bus from the Bronx to 34th street.

The 1, 2, or 3 Trains all stop at 34th St. You walk across the mezzanine till you get to the LIRR main waiting area then you go up the escalators hang a right and go past the Shoe shine stand on your right as well. You should see or smell it by then. Don't know about the bus... maybe an express bus stops by 33rd or 34th street. Go to MTA.COM for info.
