On-mountain dining is a luxury that not everyone can afford.  Buying lunch for the whole family? You can rack up quite a bill at any of the on-mountain eateries at Colorado resorts.  Now Keystone has some nice relief to the wallet drain: the $5 value meal. Available at any of the cafeterias at Keystone resort, the deal includes a drink and one lunch item that will vary depending on the day.  This Saturday it was a fully loaded backed potato and, while my picture doesn’t do it justice at all, it was pretty delicious and definitely worth the five bones.  In fact, it was so big I couldn’t even finish it.  This is a very welcome change of pace and a really nice deal.  (fine print:  after taxes it actually costs you $5.75)
