The place is busy for sure
The only thing I'm concerned about at this location is the number of derelicts that swarm the streets outside and occasionally beg and berate customers or cashier. Personnel have been prompt with some but not all and some of them do lay waste to the restroom and do not clean up.
I don't blame the Burger King staff for that but it would help if restrooms were secured at this location so that customers would be able to have a safe and clean experience that does not sour their appetite.
This Burger King is available via the B41 LCL at Flatbush Av & Albemarle Rd (or a five minute walk from Church Av & Flatbush Av via B35 (Both) and B41 LTD). Church Av (2)(5) station and B44+ is three blocks east and Church Av (B)(Q) is about three blocks west at East 18th Street.
