Suffice to say, had I not been in catered I do not think I would have had my friendship group at all. Some of my fondest memories are the ridiculous chats we had at lunches/dinners, and it would've been much harder to meet some of them as they were different blocks etc. [ie - catered can be more sociable]
Also, it means a year of eating relatively decently
Personally I also think for first year it takes some stress out of packing when you then also need not consider giant quantities of food and utensils etc., where to buy stuff on the first day..
Then in later years you only need sort it out communally with your housemates, once you're established, and need not have multiple toasters...
(For instance between us this year, I didn't buy any utensils as I had a few to bring and we all share - rather than all having too much)
However I would add a few caveats.
If you are likely to have long days and miss dinner, or never go to breakfast or lunches, perhaps not worth it. (I personally went to brekkie, then went back to sleep).
If you're very picky, or want to eat healthy, again, likely to be an issue - there are healthy foods (salad bar esp is fab), but a LOT of carbs.
Otherwise I'd advocate it. Plenty of time to learn in later years, plus you do still need to cook some meals yourself in catered (lunch and weekend evening meals) (albeit with only a microwave in some halls)
