Few new restaurants sprout in Milwaukee as a direct result of a civil war. Few Wisconsinites get married to a soundtrack of artillery fire in the distance. But those are the roots of Arin Bert Coffee & Grill, which recently opened in a Downtown storefront that over several decades has housed Finch's Corned Beef, Five Dollar Deli, Philly Way, Wingz and Amazon Pizza. The address is 222 W. Wells St.
