Connel, I was just at that party shop you recommended in January. Not as large a selection as back home, of course, but a start! And if you want the works you can order at Birthday Express in the US.
Florida Bakery (the one in my neighborhood at least) on Zhong Shan N. Road Section 3 has a small selection of party goods from the US and some really nice candles for the top of your cake. Not much of a selection but if it’s a very small party, and if it’s more convenience, you can pick up a set of plates/napkins/cups for about NT600/8 people, or about 350-450 for 8 plates + napkins.
Picked up a Party Box catalog at the Community Services Center in Tianmu. Their website and catalog are in Chinese but you could try giving them a call to see if you can order by phone. The catalog says, “We speak English!” 2834-8642 or 03-280-6809 service@partybox.com.tw
I have a friend who does children’s party entertainment. She is Taiwanese and speaks English well enough (if that’s important to anyone) to keep kids entertained and having a blast. She used to work for Gymboree, now teaches “Lasy Children’s Engineering” and kids LOVE her. Call Amy if you’re interested at 0953-806-797. She also does balloon animals. I can’t remember her hourly rate, but estimate 1000-1500/hour. Also keep in mind that if you have a lot of kids at a party, balloon animals can easily take up a lot of time.
Just remembered a few possible party venues:
My Story Island also does birthday parties. The minimum is NT10,000 if I remember correctly and you’re able to bring food, and your guests enjoy the storytelling. When a friend and I visited them in December they said the space was suitable for about 50 people.
There’s also Playspace. I believe they also have a minimum of NT10,000 or so to book the space for your party but food is not allowed. If you like Playspace though you might be able to ask if you can have cake in the little snack area.
Party rooms available at these play places too, I think:

Yu Kids Island In Taipei there are locations in Neihu and Tianmu.
Things change so quickly in Taipei though, so call for details!
