I can't answer about food because I actually don't eat the hospital food but I don't have an ED so it is different.
Every unit is different so I can answer for where I am :)
I have my own bedroom, it has a bed, wardrobe, bedside cabinet, a chair and a sink in it. Most things are 'anti-ligature' which means there are a lot of curvy surfaces and the door knobs are a bit odd! There are showers and baths, the showers and activated by motion sensors as are the sinks and toilet flushes.
My door locks behind me, which means it is safe whether I am in or out of it! Obviously the staff can override the lock (as they can for the bathrooms etc). They check on your regularly, including at night (they just look through your door, they don't wake you up). Your observation level can change depending on how you are, at the moment I am on constant obs which means I have someone with me all the time, but most people on the unit are checked once an hour. They can increase your observation levels at your risky times, so for example if it is an ED unit they might observe you more closely or ask you to stay in a communal area for a certain amount of time after meals.
I have my own laptop and a dongle here (but does depend on the unit), I also have my phone. You are not allowed chargers in your room but they will charge things for you in the office. I have a Kindle, colouring in, puzzle books, magazines... I also play Scrabble, cards, do jigsaws, crafty activities, sometimes with other patients, sometimes with the staff. There are specific staff who organise activities, but weekends can be quite dull. I watch TV a lot! There are lounges to sit in and tables and chairs if you want to do something at a table.
There is a laundry here but my husband takes my washing home for me. I have my own towel here and can change my bedding whenever I want. There are always fresh towels and linen available. I have all my own toiletries and make-up like I would at home. Razors are usually supervised but you can shave your legs etc.
I am sectioned and have quite limited leave (time away from hospital), so my husband mostly visits me here. He comes every day and they are pretty flexible on visiting. My friends have also visited me. Sometimes I find too much visiting a bit overwelhming so be aware of that! People here have their children visiting them, or they go out to visit them.
I self harm which has some similarities with ED, with other SIers I have to be very very aware of it becoming a competition. One girl here started to copy me which really upset me. You have to try really hard to focus on yourself and your recovery.
This is crazy long sorry! I hope it is helpful.
