At Rose's Bed & Breakfast the Chosen One can order some interesting meals and have the option of entering a brahmin fries-eating competition. If the player breaks the record he/she will become poisoned - the fries are really brahmin testicles.
If you order a glass of water for $1000, you get a cookie with it. Eating a wasteland omelet - Rose's specialty - for $25 will restore your HP to full and cure poisoning.
With Intelligence of less than 4, the player can get a free omelet every time you talk to Rose (but nothing else).
Kill the "chicken": The fenced-off building to the left of the Bed & Breakfast with the rocks piled in front of the door is the "chicken" coop where Rose gets the eggs for her omelets. You can blow up the rocks with explosives, revealing a mother deathclaw which will immediately turn hostile. Once the deathclaw is dead, Rose will no longer sell any more omelets.
Rose is mentioned in Fallout: New Vegas by her great-niece Jas Wilkins in Sloan. During dialogue it is revealed that Rose taught Jas the recipe to make wasteland omelets using deathclaw eggs, however those omelets ceased to be made in Modoc when "someone" shot Rose's pet deathclaw in the eye.
