We had the opportunity to sample all three ways of traveling on segments of this route (Wilderness Express, Alaska Railroad Gold Star, and Alaska Railroad Adventure Class). For this segment (Denali to Anchorage), we went in Adventure Class to save some money on the return. The views, as always, were stunning, but the service/experience was not good. The car smelled like onions or garbage, and aside from the overhead rack (which kids can't reach) there's no storage at your seat — why no seatback pockets?
Worst of all, the food options were *terrible* — when we saw the menu (hot dogs, burgers, sandwiches) we thought it would be OK, but the way it works is you get a pre-wrapped cheeseburger out of a fridge (no toppings available), pay for it, and then you microwave it yourself. You microwave a cheeseburger, that you paid $10+ for, and it tastes like plain school lunch food. And just to add insult to injury, the credit card receipt has a tip line. For the cheeseburger that you have to microwave yourself. Even the non-microwaved stuff, like the turkey and cheese sandwich, tasted like it was a day (or more) old. I know it's not sit-down/full-service/cook-to-order dining like Gold Star, but really? Come on. You're on the train for 8 hours (or in our case, 9.5 because of a delay). The food options really need to be improved — at least have hot food be actually hot. Gas stations have better solutions for serving hot dogs. McDonald's cheeseburgers would be a huge upgrade.
