Ever since I first told you about the new project from the Voltaggio Brothers, that was coming to The Gallery at 1315 3rd Street Promenade, a great many of you have been anxiously checking for details.  (Eater filled in the gaps.)   Well… cue the stampede:  Voltaggio STRFSH is now open as of two days ago.  Currently, they are only open for lunch, but they plan on dinner service soon. The concept?  You start with a choice of swordfish or salmon.  Then choose a rub, a smear, and toppings before it all lands on a toasted potato roll.  Or pick one of their already designed sandwiches.  An ABC license is posted, so libations are on the way.  You’re welcome.
