RIB hutt was a place to eat on Coruscant. It was run by a Hutt whose name is unknown, and it operated during the era of the Galactic Republic. This eatery was famous for calling itself the "Home of the Rancor ribs."
Darth Maul, when he was just a young man, once collided with the restaurant after taking a skimboard without permission. He ended up crashing directly into the Hutt who owned the place. After getting back on his feet, he was able to take a lightsaber from a Jedi who was eating there. He then used the lightsaber to control his fall after leaping from the side of the structure.
The restaurant's name probably alludes to Pizza Hut, the real-world restaurant franchise.
A majority of the servers were Twi'leks, and one of them was dressed in attire similar to the slave outfit worn by Leia Organa.
