Burger 21, an upscale, Tampa-based burger chain, will sling free cheesy patties to patrons who join its email club, B21, before Wednesday.
After the complimentary offer reaches members' inboxes, they may redeem the deal between Wednesday and Friday with the purchase of another burger, salad or dog.
There's three Burger 21 sites in the area: one in Carrollwood, New Tampa and Westchase. Those who subscribe to the B21 Club in advance will also receive a free fry deal to use during another visit.
The fast-casual restaurant, which crafts 21 kinds of beefy delights, is offering the burger deal in observance of National Cheeseburger Day Thursday.
Every day is a foodie holiday, OK?
