Little light shines in Luigi's House, complete with thick drapery, few windows (many rooms with none) and dusty old wine bottles hanging from the ceiling. I've eaten at this Portillo's chain restaurant 3 times, and each time felt the food was mediocre. The waitstaff was helpful, but overworked, and other than the neat looking "house" of Luigi's, right on Route 59 in what feels like Naperville (which is across the street), this restaurant is more expensive than Olive Garden, with food that is only marginally better. I'd give the nod to Olive Garden atmosphere (I know, I can't believe I wrote that either), and certainly to prices, and to salad and breadsticks. The actual pasta meal--some with fresh fish--are slightly better at Luigi's House.
Chianti's on Third Street in Geneva, Za Za's Trattoria in St. Charles are much better than Luigi's--so for those looking to compare to those restaurants, you will be disappointed in Luigi's.
Frankly, Luigi's feels like you're dining at Epcot Center in Disneyland, where it's a "made up" feeling, like a stucco and Animatronics new, made to look old, place, filled with Aramark dining service food at high end prices. Seriously, you will feel like you're in the land of make believe, and the food will be unmemorable, and when you were done, you will realize that--like Santa Claus and the Tooth Fairy--that there is no Luigi, and you just paid to eat uninspired food in a fake atmosphere and you will long for a "real" restaurant, manned by real people and a real owner and a sense of uniqueness that, despite its efforts, is completely sanitized out of Luigi's House in Aurora/Naperville.
