Brownies Hamburgers has been a staple of Tulsa's fast food scene since it opened in 1956! The restaurant is known for their homemade root beer, onion rings, meringue pie, and of course, good old-fashioned burgers.

Art by Betty Notter Protect your furniture from moisture with these amazing, durable waterstone coasters! They are freakishly absorbent for both hot and cold drinks, and the beautiful Tulsa in Ink artwork is fade resistant. To clean your coasters, prepare a solution of 3 parts hot water (not boiling) and 1 part bleach. Soak the coasters overnight. Rinse, lay flat with the cork-side up and allow to air dry. This process may be repeated to remove stubborn stains such as coffee, wine and cola.
