This isn't very accurate. What one day are you downtown? I work downtown five days per week and frequent Basil, Local Bites, and South Union two or three times a week on a rotating basis. Monday and Friday are straight up dead for people in the skywalks. The other days have more people but can still be pretty sparse.
I'm not there on Monday or Friday. And I wouldn't say that any of those places are dead the times I am there (and I'm at all 3 as well). I don't remember how busy any of them were pre-COVID. But I wouldn't call any of them dead in the middle of the week.
