Loretta offers the team "fresh chicory" which is a coffee substitute popular in the South, especially in New Orleans. It was widely used by both sides during the Civil War when real coffee was scarce. Chicory is a relative of the dandelion family.
Sebastian's undercover alias is "Johnny Hooker", which is Robert Redford's character in The Sting (1973). The OTB scam the team pulls on Garcia is similar to, if not a loose representation of, the con Hooker and Henry Gondorff pull on Doyle Lonnegan in the film.
