Steins;Gate: Oukoubakko no Poriomania is a special episode following Okabe and his lab members visiting Makise Kurisu in the USA 6 months after Okabe reached Steins;Gate timeline.
If you enjoyed Steins;Gate then it is very likely you will enjoy this episode as well, now onto the review.
As far as I am concerned it wasn't stated whether it is canon episode or not.
My positives:
1, Story: We follow recollections of Kurisu memories from Alpha timelines. We get to hear Kurisu, like Mayuri in Alpha timeline has dreams of her experiencing many things, including exchanging kiss with Okabe. Oukoubakko no Poriomania serves as a finale to Kurisu and Okabe romance with humorous input and some 'easter eggs'. The story itself is structured pretty well with humorous moments that work quite well. I think this episode has managed to deliver a good finale.
2, Art and Music: Pretty much the same as Steins;Gate, so if you enjoyed anime, then you should enjoy this too.
I didn't find really anything that would be annoying or bad, just a few nitpicks here and there.
Overall it is 9/10.
