In watching Rick’s tour through Rome, May 2012, he stopped at a restaurant called Trattoria Enotica, which only served lunch. Is that restaurant still in existence? If you have contact information to I’d appreciate it. Thank you, TOM.

After years of searching out my favorite European restaurants, I've found a few universal indicators for a great eating value. And a place like this [Enoteca Corsi] has them all.
The best eateries are little family run places that cater to locals. This one's open weekday lunches only. At a glance you know this place is a find: limited selection, hand written menu — in one language, packed with the neighborhood gang. Each day there's a special — today it's spaghetti carbonara. Simple, tasty cucina casalinga — that's home-cooking Roman style.
Google tells me that it's still open and here is their menu:
