Which Wich, a new sandwich shop at 4300 Wilson Blvd in Ballston, is planning to open its doors on Tuesday.
The store is the chain’s first in the D.C. area, and the third fourth in Virginia. Which Wich touts its selection, with over 50 sandwich varieties and more than 60 toppings — offering some 56 trillion possible combinations. There’s also a Coke Freestyle machine at the store, with more than 100 drink and flavor combinations.
