It would be nice to step in there periodically to get a bottle of water when I am thirsty rather than walk all the way to the kitchen.
For storms lasting long enough you'd need drinks, it's likely you'll have plenty of time to prepare.
I wouldn't waste space in a "safe room/ storm shelter" when you can put a small refrigerator in any room you like and run it off house current.
If you're actually talking about a "bomb shelter", then a 12 volt refrigerator might be worth the investment since you could spend weeks inside.
