Royal Laurel Meals 2022 on (post Covid)

There are plenty of meal photos. I personally posted a late night departure from Taipei to Munich that I took last year. The service will be similar to all long haul flights that depart after 10pm. The supper is designed to be served more efficiently, as EVA AIr presumes most passengers want to go to sleep. Honestly if you fly business, I can't imagine you going hungry. The crews will always serve you the noodle soup or hamburger from the mid flight snack menu immediately after supper if you are still hungry. Many people skip the first meals too so they may have extra main courses lying around too. I am not a fan of EVA Air's Taipei lounge, but since BR 16 departs midnight, I presume you will have a normal dinner in the city before heading to airport.

For premium economy and economy class, EVA Air serves supper right after takeoff on those late night flights, and then a breakfast/light meal prior to arrival. They sometimes start three hours prior to arrival especially on westbound flights, as most passengers will get hungry earlier due to time differences. The sandwich service is still ongoing and there are light packaged snacks available too.
