Ah, well, know it's in Krebbs, thought it was Italian, was thinking Pete's Place too, but it's been about 15 years, so no telling where I was - a college roommate was from around there, her family took me to dinner once when I visited. I just remember a not-too-fancy looking place with good spaghetti. Giacomo's sounds more Italian than Pete's Place, doesn't it?
Keshia, if you like Italian, there's a place on I-35 about Hefner or so called Papa's Lil' Italy that's worth a try. "Papa" himself died a few years back, so it doesn't have his same touch, but it's still good food, run by his son-in-law now, I think. I believe the same family still runs another OKC restaurant called Papa Dio's also.
