Just got back from the pre-screeening and I have to say this was worth all the buildup.
Tthis is the kind of production Joss Whedon does when the studio execs let him do his thing. Hit all the right notes for an Avengers movie. The whole theater burst out clapping spontaneously at one point, and plenty of humor (but not enough to interfere with the serious) to be found. All in all, a fantastic film, and one that I am going to see at least once more.
As for the second scene, there was one, but it was just the team chilling in (what was presumably) that restaurant that Stark suggested they go to after the battle.
