We were there yesterday, though it was our first time at Mullet. There were two places renting chairs,as best as i could see. We rented from Rosies and ate there as well, burgers were fine , though it is definitely a shack. I did check out the restroom. You pay at the bar of the other place. The bar looked new, and fairly sturdy in contrast to Rosies. They had power and were making drinks with a blender. I think they had a separate small building that they used to cook food. The bar, restroom, and kitchen all seemed of similar construction. Btw, we went to Mullet based on reviews here. All i can say is wow. The water was beautiful blue, snorkeling was fine at end of the beach, and the waves were invigorating
