Hard to find, as the first 2-3 clerks in the mall had not heard about it. Best way to find the small shop, is to ask for the food court.
Be ready to wait for your food as it is prepared after you order. I noticed some people ordered ahead and showed up to pick it up.
Food was ok. But the low prices earned another star. Doubt that we'll go back. Next time we'll probably try another pupusa place.
