I definitely paid tip at the Yen! Though I paid with my international credit card. The tip is optional but if they give you a receipt to sign, there is a tip field
I once brought flowers to a cute girl on a blind date. I’d only seen her photo. I had in my car a tablecloth, matches and candles with me and took this cute blonde to McDonald’s. I thought McDonald’s would hassle me about the candles but they didn’t. She loved it; we went straight back to her place
Service fees are normal in Taiwan. If you’re given the opportunity to tip, it’s voluntary. No establishment charges you a service fee and a tip, as you stated.
I have been to French restaurant in Kaoshuing, NT$10,000+ for 3, with wine and service change, so it’s possible (to be fair I think the wine was NT$3,000+, did not check the details or price very well)
Advanced booking yes, semi private meal. Will not go back not worth the price to me. Food was ok, but not great. Better just eat in France haha. It was not a first date (I would never do this on a first date)., I was with a local long time friend and French-American visitor. My local friend, she was also not impressed. The next trip when Frenchie came, we had local dumplings and local wine at 10% of the cost and it just more enjoyable and relaxing.
I’m not Taiwanese, but Chinese American. Yes, everyone is supposed to try to pay, because otherwise you’re just freeloading. But the one with the most “face”/status is supposed to pay, like the family matriarch/patriarch, boss, etc. (Obviously there are exceptions, like if it’s your first paycheck and you’re treating your parents.) Some will even arrange it before dinner/while making the reservation.
So if you’re a “manly man”/someone in charge of your own life, you should figure out a way to pay. Some women care and some don’t. I’m not Taiwanese, so can’t say how many Taiwanese women would care.
