At the beginning of the episode the restaurant's name is clearly displayed as "Dillons Lounge" (on the scrolling marquee) and "Dillons Restaurant" (on the canopy). Later, after Gordon Ramsay changes its name, the new signs and canopy say "Purnima Dillions Restaurant" (note the errant "i" in Dillons).
In a followup episode where Ramsay revisits the restaurant, the spelling has been corrected to "Dillons," removing the extra "i."
