Good choice with Howlin Ray’s! Get there early, though. Before they open. The line can easily grow to an hour or more within 15 minutes of opening.
If you give up on Howlin Ray’s, or maybe just want the mother of all bang-bangs, head around the corner to Little Jewel of New Orleans for po’ boys.
Also, have you been to Gjusta in Venice? If not, that’s a must imo. Try the porchetta melt and prime rib butcher sandwiches. Soooo good.
