RE: International Restaurant Row
I think Washington Street in Hoboken NJ, would qualify.
The city of Hoboken is only a mile square, but packs a great punch of culinary variety. Especially on Washington St.
Italian restaurants as well as pizzerias, Asian, Asian fusion, Bagels, Bakeries, Bodegas, Cuban, Delis, French, German, Greek, Hot Dogs, Indian, Irish Pubs, Japanese, Juice Bars, Latin, Mexican, Middle Eastern, Produce a plenty, Spanish, Steakhouses, Tapas, Tea, Subs, & Vegetarian ect., all within a nice little walk up & down Washington Street. Not to mention many other places on Sinatra Dr, and many other "side" street restaurants off the main "drag" of Washington St.
A VERY short Path train (5-10 minutes) ride from Manhattan.
