Serafina SF
Serafina SF
San Francisco
Against all odds, we have opened up our newest restaurant, Serafina, This little gem of a restaurant, perched on top of Nob Hill, has truly been a labor of love, as we were set to open at the end of February, and then had to do so during the ensuing pandemic....We are so excited about Serafina, which has been a concept in the making for many years for us. Serafina was Maurizio’s grandmother, and the name of her eponymous restaurant in the heart of Trastevere (Rome), where Maurizio first began making pizzas at the age of 14. She was a tough woman and wonderful chef.. an inspiration for his love of cooking then, and inspiration of how he is determined to persevere despite the difficult circumstances of today. We hope to create a warm, elegant space where neighbors and friends can come together. We have an amazing team with our partner Giuseppe Terminiello, the co-owner of Piccolo Forno with us (we also own Ideale, in North Beach as well), and Umberto Cannarsa, an accomplished and incredibly talented chef from Rome, who had his own successful restaurants there.

Rock 'n Roll Team Building
Rock 'n Roll Team Building
Multi-city
Connection. Creativity. Chaos (the fun kind). Available all over the USA! Forget the icebreakers and trust falls. This is team building that cranks up the volume and gets your people actually connecting — not just collecting another tote bag. We take your team, hand them a mic (sometimes literally), and turn a room of colleagues into a full-blown rock choir. It’s equal parts live music, laughter, storytelling, and spine-tingling harmony — all tailored to your event. Here’s What You Get: • 🎸 Live Music that kicks like a drum solo at Wembley • 🎤 Storytelling that hits the heart (and the funny bone) • 🎶 3-Part Harmony Choir — no singing skills required, just good vibes • 🤘 Audience Improv — spontaneous, unforgettable, and never awkward • 📝 Custom Song Creation that ties your event together with a chorus your team will hum all the way home Perfect for: • 🚀 Launching big ideas • 🔋 Energizing the middle of a long agenda • 🎉 Ending on a high that actually gets remembered We’ve done this with 10 people. We’ve done it with 2,500. Either way, we bring the same stadium-worthy energy. We’re fronted by Grammy-nominated INXS frontman Ciaran Gribbin, backed by world-class musicians, and powered by pure rock ‘n roll spirit. This isn’t “team building.” It’s a shared experience that gives your people goosebumps, grins, and genuine connection. Ready to shake things up? Let’s talk. "Best Team Building I've ever booked. Ciaran and the band were great." Arrow Electronics "It was absolutely the best team event I have ever run or attended." Lamb Weston "I can honestly say that Rock 'n Roll Team Building is the best event experience I have ever seen at a conference." Jazz Pharmaceuticals
