When the movie was originally announced there were two photos going around with easter eggs at a diner, one depicted Sindel and the other Cetrion soda. When the movie was released these appeared to be missing.

However, thanks to Dingus for pointing it out in my screenshot where a guy gets knocked out by ice, you can see they moved the sign to the corner of the diner's sign. It appears on the left of the screen at 21:27 timsestamp on HBOMax.
