As a 30-year fan of Little Lucca deli in SSF, where I first encountered Dutch crunch bread and LL's famous garlic sauce, I noted a mention on HO that the original owners have a new place, Teani’s Deli.
Bless 'em for having head cheese and zampino on the cold cuts menu. Teani's is in the same location as its original grocery store. It is on the same block, same side of the street and only 272 feet away from Little Lucca sandwich shop that continues to operate today. The article linked below that I found on a community news site has the details.
According to posts on the Everything South City FB page, Teani's has crab salad and shrimp salad on Fridays. Please report in when you try this spot.
