Robbie Porter should know. The 25-year old Fremont, California, resident has chowed down on the Italian chain's fare twice a day on average for the past month after securing a Never Ending Pasta Pass.

He's one of 1,000 people who snagged the pass for $100—a promotion that entitles him to an unlimited number of certain pasta entrees and toppings from Sept. 22 to Nov. 9.



"I'm still enjoying it, but obviously I'm doing it for a cause" (to raise awareness of Crohn's disease), Porter said by phone. "It's not as bad as people think. It's decent, but I wouldn't say it's spectacular."

While Porter isn't tired of Olive Garden, he said it's difficult to find time to go since it's not convenient to his office.

Porter's quest started as an office joke because the Credit.com sales operations manager is known as someone who loves to eat.

"I decided I couldn't just go and have a gluttonous time," he said. "I actually had to do something positive with it."

Instead, he's using the publicity to raise money for research for Crohn's disease, an inflammatory disease that targets the digestive tract. Porter, who has suffered from Crohn's for five years, notes that many people tend to avoid discussing it in public. (Read more about Porter's experience and his fundraising efforts on his blog here.)

So far, Porter estimates he's eaten about $800 worth of Olive Garden food and spent about $20 (yes, $20) in tips for the meals, which he gets mostly via takeout.
