The only good thing about Tangyue was the view from the room.
I've worked in kitchens and my husband has too as well as in hotels and this place felt like an episode of Kitchen Nightmares crossed with a David Lynch film and Faulty Towers.
On the Trip app they said to contact the resort via email to arrange a shuttle from stations or airports. I found 2 email addresses and emailed them both multiple times with no response to anything - that was the first red flag.
They had written our check our date incorrectly and it took two conversations of 30 minutes each to confirm that we didn't need to pay for another night as we were checking out on the day we initially requested. They kept saying that you'll need to pay online for another night but we didn't need one. Finally that got sorted.
The first night we bought the set menu for dinner at the restaurant and they charged us, but then said they made an error in putting the price in their system so then they tried to refund our card and then tried to charge us immediately but the refund had not gone through. Very bold assuming that everyone has two lots of dinner money in their account.
The kicker for this was the set menu was so terribly bad (an attempt at Western style fine dining - 6 courses for bad tasting and bad quality food that was truly awful and fine dining is kinda boring). The first course was chicken wings stuffed with cod roe - the chicken was cooked long ago, not kept warm and served cold and the roe was so gross and artificially pink. The main was a serving grey pork chops that with the translation was alleged 'Iberico'. We could have excused the food if it was not expensive but it was it was ludicrously expensive for how bad it was.
This entire fiasco was course not helped by language barriers and using Google to help with translating but this took 45 mins to sort out and we ended up having to pay for the dinner twice. And my husband got food poisoning from the food and was ill all night long. So husband payed for it 3 times technically. They offered us a free cup of coffee for double charging us rather than saying we can sort it out another time but little did they know we had paid for all inclusive breakfast so the coffee was already free.
The next day, husband staying resting after his food poisoning. There was not much to eat and we didn't want to chance the restaurant again (the only place to get food on that part of the mountain) so we bought packet noodles and Doritos from the vending machine.
The last day of our trip, we wanted assistance to book a train back to Taipei and the girl who 'helped' us was sniffling the whole time and not wearing a mask and ended up just telling us to go to 7-11 to buy tickets.
The open-air baths were pretty nice, but they had heaps of mineral build-up everywhere and dead leaves and detritus, so it felt a bit gross. Then I got the flu from staying there.
Maybe we stayed at a strange off-peak time of year and the kitchen was doing experimental dishes, and the staff they had on where not their normal staff. I don't know but I strongly recommend you avoid this place.
