Yesterday I walked by (the former) Noi in Noe Valley on 24th at Castro. Now it's called Lupa. Not having heard any positive things about it, I never ate at Noi during its short, two-year life. The decor at Lupa seems to have changed somewhat toward more casual. The Italian menu posted on the window looked somewhat interesting, with prices in the mid teens. I don't know if the name indicates some kind of Roman/Lazio cuisine.
Anybody been there yet or know about the switch?
