Depends on if you are looking to get the best $$$ value from your
DDP or just use it to make life a little easier.
If you are looking to get the best $$$ value from it, I would do Akershus for lunch and Les Chef's for dinner, since lunch at Akershus is going to be more expensive than lunch at Les Chef's, Akershus lunch will cost you about $35 for an adult and Les Chef's prix fix lunch menu costs about $20 (not saying you will use the prix fix menu, just used it as something to compair).
Also, both meals can be pretty rich and filling depending on what is ordered. Might I suggest getting a late breakfast ADR for Akershus and an average-later dinner time for Les Chef's? If you book these as lunch and dinner, you may not be able to space them out far enough apart, which could ruin the dinner experience.
Another thought, since you mentioned Epcot days (as in more than one) would be to do the 2 meals on different days. Maybe do Les Chef's on the day/night you plan on exploring the WS and do Akershus on the other day since Norway isn't too too far into the WS.
