Shake Shack has opened its easternmost Long Island location, in Riverhead. The space in Tanger Outlets Riverhead, opened in late June with fan favorites on the menu like the shack burger. The burger joint also launches with the chain's limited-time West Coast menu featuring burgers, chicken sandwiches and loaded fries. A regional marketing manager said the brand wanted to expand its reach "and get into new communities. It’s the furthest out east ... and its distance to the next Shack over, especially when you’re talking about New York and Long Island, is a little bit greater than most." More at the link in bio.
