We dined at the Zeffirino since we were staying in the Venetian. It was quite a treat. It is in a nice location, near the Grand Canal in the Venetian. If you arrive early, you can request to sit on the second level, overlooking everything. There was a musician who also serenaded us during dinner, which was cute. The food was decent, it could have been a wee bit better, honestly, and the service was excellent. This is a very nice option for Italian in Vegas.
