Waves Said Pandaren Noodle Guild, here! At your service. (Thanks for the shoutout, Khoovi. Free ramen coupon for you! 
)
MG Alliance side is a very bustling place. There are many collab groups of guilds that work together to make fun, public events for everyone on a regular basis.
While guild hunting, I also suggest you keep an eye out for these public events here on the forums, in specialized forum posts for RP events, and in discords for RP event listings.
In particular this month, (as you can find in any of those places) there is a SW Weekly Market every Monday, a Teaspoon teahouse event for the ‘Love is in the Air’ holiday, a Pandaren New Year festival, an IC Job Faire, a ‘Crucible of Might’ social-PvP tournament, a ‘Love is in the Air Bash’ public party, lore-based storytelling events, my own Om Nom Noodles’ weekly noodle shop RP, and many more. 
So welcome. We hope you enjoy your stay.
