We had breakfast at the AK RFC last October, when the breakfast vouchers were at $17.50 for adults. DH & I each used one, & we both ordered a large OJ (included). Since the vouchers also cover an entree and a side, I got the breakfast burrito meal (not what it is called, but I can't recall the name) - that is scrambled eggs with peppers, cheese and sausage in a wrap, served with seasoned beans & one of their tiny lemon poppyseed muffins. I ordered sausage patties as a side.
DH had the Tonga Toast (French Toast with bananas and nuts) which came with a meat choice and he also ordered a side of scrambled eggs.
The voucher covered it all including tax and tip, and for a total of $35 paid for the voucher, the bill with tax was around $42 (before tip), and we felt that we saved a lot. However, we had more food than we could eat, and it would have been much more worthwhile if we had a third person to share with.
We love the AK RFC for breakfast; it has become one of our must-dos for each trip, even though most days we just eat breakfast in our room.
HTH!
