Spaniards. They often eat dinner very late by US standards.
I grew up (in the USA) eating dinner around 7pm. We almost never ate dinner or 5 or 6pm.
Today, it’s variable. If we’re doing leftovers, we eat on the earlier side. It’s 6:30 now, and I just finished cleaning up after dinner. If the meal is more involved, we may eat at 8-9pm. It also depends on what the day held for us. Sometimes we’re busy outside, and don’t even get inside until sundown (which happened a lot the past few weeks). Cooking then means we aren’t eating until 8pm, at least.
