My old thermos broke, so I'm looking for a good lunch container to take hot foods to work that STAYS HOT. My office doesn't have a microwave (don't ask - I almost wouldn't have taken the job if they didn't have one. Just goes to show you, you have to remember to ask the right questions when you take a new job!), and I've forced to fill food up into a thermos to take it to work. I saw the Zojirushi Mr. Bento Stainless-Steel lined Lunch Jar on Amazon:
Its a little much, but anyone try it yet? Other than that, any recs for ones that keep food hot for at least 5 hours would be greatly appreciated.
