Montague Street (between Henry and Clinton -- on the South side) is poised to take a massive culinary leap forward -- apparently a Five Guys is coming!
For those who don't know it, Five Guys was a small amazing burger and fries place in suburban Washington DC. They've grown from 2 storefronts to dozens in the last 5 years but I don't think the quality has suffered much.
From what I recall, the burgers are Shake Shack quality and the fries are unparalleled -- akin to Thrashers Fries for those who know Thrashers from the Maryland shore.
Keep your fingers crossed. Between the new french place on Henry, Hibino just over Atlantic and now Five Guys -- maybe Brooklyn Heights has turned the corner!
