When my grandmother was unable to live on her own we moved her up to where we live. She had a good amount of money stashed away, so shopped every nice facility in town, and picked what seemed like the nicest one. While I would say the food didn't look as terrible as the picture in the OP, it wasn't much better. Multiple other issues at these places though, staff not helping, not giving meds on time, falling and not getting assistance for hours. One of the worst was falling, having to go to the hospital, and never letting emergency contacts know. We found out when the hospital called, because her charts didn't seem to match up. Turns out they sent the wrong charts to the hospital. Thank god she didn't have any allergies. We ended up moving her to another facility that was even more expensive, and promised none of these things would happen there. Turns out that wasn't true, so my parents finally ended up moving to a new home where they could finish the basement and build an apartment for her with full time care hired to come by.
I used to always think if you had the financial part of old age figured out you'd be okay, boy was I wrong.
