Any Publix will carry Boarshead meats.
Unless you want packaged Thomas' or Lenders bagels...none of the grocery stores carry decent bagels.
There is a small bakery at the intersection of Turkey Lake Road and Sand Lake Road (5 minute drive from Disney) called Delish.
They make the very best bagels around.
Most bagels in central FL are not something most people would recognize as a bagel. Delish actually makes real bagels.
