I am often thinking about food, it will likely be incredibly bland and not very varied. Plus you'll spend probably most of your time indoors. You won't ever lay on a beach listening to the sounds of the wave, or walk on dry leaves in a forest anymore.
There are a huge number of humans on earth who spend their lives in urban centers and also never have those experiences.
Speculating about the quality of food on mars is pointless; we have no idea how that will work. If you can afford regular equipment shipments to mars (which is probably what a mars colony will require with near-future tech), it would probably make a lot of sense to ship up a bunch of spices. They have a very high utility/weight ratio, which is why they were the impetus for the foundation of so many historical colonies.

Those people can and do at least go to parks.
A better analogy is that it would be like living in an underground bunker on Death Valley, with periodic excursions out to the desert, while wearing a spacesuit.
There are a few theories for getting magnetic poles going on Mars. With that, and some terraforming, and a whole lot of time, they could eventually have a breathable atmosphere.
Of course this will take many hundreds of years and need a bunch of new tech.
Anyway, for now, we can breathe the atmosphere when we go outside. That's not what it's like on Mars. I don't think I'd enjoy that.
