Dropped in on the test this evening and here are some observations:
These stairs appear to be double-sized, which I'm guessing is why the bottom one is smaller than the rest.
You've mistaken the doorframe for part of the door, here, as so many have before you. Also the reflection in that window looks awfully bright, possibly the result of using a cubemap that's elsewhere.
These plates are awfully low-poly considering they're just simple cylinders. It's especially unnecessary given that this is the spawn room; you can afford to pig out on detail here. Same with the bar stools (not pictured), which I think might be the ones from Watergate? But if not, yeah, need more polys. On a related note, that sink seems too shallow but maybe I'm just used to the sinks in home kitchens which are meant to hold dish tubs.
The bottom step here is also half-sized, suggesting one of the floors is off-grid.
I guess these doors are a stock prop from Kong King? Because, again you've got double doors with a frame in between them but also the handles are both on the same side.
One last general thought: Switching to the shiny floors from Mann Manor would class up those restaurant/bar rooms a fair bit. Alternatively, Timberghost made a less rough looking wood-floor texture ages ago that
I reskinned in various colors; you might want to try those on for size. (Not the shiny versions, though; I didn't know what I was doing and they look a lot worse than I had expected and I'm going to re-up the pack with them removed as soon as I'm back on Windows.)
