It was a full house in more ways than one at Fabio Viviani’s bustling Italian eatery, Siena Tavern last night; actor Bob Saget, was spotted having dinner with his girlfriend Kelly Rizzo on Wednesday night. The couple dined on the newly added branzino dish and pizza in which Saget was overheard saying, ‘It was the best pizza he has ever had.’ Friend of the actor, Jim Gaffigan, later joined the duo during their two-hour dinner. The group sipped on hand-crafted cocktails and talked briefly about the “Chicago Ideas Week” which was the reason for Saget’s Chicago visit. The night ended with Saget and Gaffigan taking a photo and joking as he captioned it: My friend @JimGaffigan has never looked better. Dang I love Chicago!
