I’d forgotten about this thread! Thanks for the resurrection. I have a lot of updates.
We found a place that I find acceptable, though not ideal. It’s called 青青食尚花園會館 (simply Chin Chin in English) and it’s near the National Palace Museum. The upside is that it’s partially outdoors and gives the feeling that you’re actually at a wedding, not a company casual drinks Friday sort-of-thing. I was partially won over by a very enthusiastic and nice sales lady, compared to the other places I had viewed.
The downside is that it’s made for weddings, and there are five venues… meaning that on the date of my wedding banquet, there could be four others at the same time! In other words, if you look out the window during dinner, you’ll see other happy couples eating away. That really upsets me (oddly, I’m the Bridezilla in my relationship), but we ended up choosing a weekend that’s no good for getting married (忌嫁娶) since we’ll be doing that ahead of time at the courthouse anyway, so hopefully there won’t be too many people there.
In the end, we’ll be hosting around 150 people, and doing it buffet style (though it’s still Chinese-style food. Still, everyone there except for the maybe 10 people from my family is Taiwanese, so no harm no foul.).
It’s set for mid-next year, so we still have a lot that we haven’t even begun to figure out. Here’s what we have no and approximate prices.
[]VENUE: For 150 people, around 210,000
[]PHOTOS: Yes, we’re doing the cheesey pre-wedding photos. Around 40,000 including clothes rentals.
[]XIBING (喜餅): I hate these, but the misses insists. We’ve budgeted around 20,000 based on the cheaper ones we’ve seen.
[]XITIE (invitations): Likely under 10,000.
[]XINNIANG MISHU (make-up artist): She wanted to skip this part and do her own make-up. I insist we hire a professional for around 15,000.
[]WEDDING RINGS: 38,000.
The total comes to 333,000 for the basics. We’ll have to spend some money decorating the place and may get a nice cake (still thinking about it), and we may also rent a liche (禮車 – one of those black sedans with wedding decoration stuff), which will push costs up a bit more.
Overall, I’m happy to say I can just narrowly afford this. Well, assuming I continue getting paid for the next several months, that is.
I’m planning a lot of unique things for the dinner so it’s not boring. I hate boring weddings. We’re going to be sort of rolling the ceremony and dinner into one event, so while people are sitting waiting for their food we’ll be reading our vows, etc. I insist on largely hosting the event myself, but I haven’t decided yet if I want to do it in English, in Chinese, or bilingual. There would be another MC to announce generic things when I’m busy with other, more entertaining activities.
We wanted to put a dance floor, but we’re afraid nobody will dance, so… 
Anyway, thank you everyone for the suggestions!
