A newer restaurant, very near where Trattoria Leo used to be on via Torta. We don't know this place personally but it looks like a large, full service, commercial/tourist type of enterprise featuring Tuscan food and pizza (which makes sense being so close to Piazza Santa Croce).
From their Facebook page:
Ristorante, osteria e pizzeria a Santa Croce, nel cuore di Firenze 1000mq di ristorazione.
Here is Cucina Torcicoda on the map - this is not "off the beaten path" as I read on Facebook :) - just steps from Piazza Santa Croce and very much in the center of Florence.
