Finally made it to the Galaxy Donuts location at Wicomico Beach, #16 in a franchise of player-built fast food restaurants. The robots who took my order were very polite.
To my knowledge this is the only Galaxy Donuts on PC, the rest are on PS4. Coordinates to visit: https://nomanssky.gamepedia.com/Galaxy_Donuts#Galaxy_Donuts_16:_Wicomico_Beach
I ate my imaginary donuts and looked out on the beautiful lake locale - a beach house, some underwater farms. This location especially reminded me of the real-life Pacifica Taco Bell: https://www.sfchronicle.com/food/article/Chalupa-in-paradise-Does-Pacifica-have-the-13379462.php
A few nice new things before the Visions update hits tomorrow: very pretty new S-class ship I bought for a song, start of a new base inspired partly by House On The Rock in Wisconsin, on a desert moon so tiny you can see its curvature from not too far above. Base perches on a mesa above a crashed freighter, a trade depot, and a holoterminus - busy area, chill planet.
Haven't found a portal in the system yet but the coordinates are 019C:0083:0764:00A7.
