We present sub-arcsecond resolution imaging of the lambda = 2.7 mm continuum emission from the young, embedded system L1551 IRS5 using the new, nine element, high resolution configuration of the BIMA Array. The observed emission arises from two compact sources separated by 0farcs 35 and coincident with the two sources seen at lambda = 2 cm. The data support the view that IRS 5 is a protobinary system with separation of ~ 50 AU and individual circumstellar disks. The approximate masses of the disks are 0.024 M_&sun; for the northern source and 0.009 M_&sun; for the southern source.
