I worked at a company that had free dinner (which it heavily advertised) but no free lunch. It was a horrible place. I don't know if I'd connect the two; it's a "small data" situation that has me making a correlation.

I'd prefer a higher salary and getting my own meals, but free dinner without free lunch is a huge warning sign.

Office gyms are usually awkward as well, but the shower is useful because you can bike or run to work, so that's a plus.
