J. Leon Lascoff & Son (CLOSED)

Founded in 1899, Lascoff moved to its “new” location in 1931. The shop hasn’t changed much since, and a collection of its original preparations and other artifacts is on display in the old-fashioned wooden cabinets, along with modern goods that include D.R. Harris grooming products and Mason Pearson brushes, as well as more prosaic pharmaceutical necessities.
