We've been going to AP for well over a decade--about twice a year--and like any restaurant, it has had its peaks and valleys. For the first few years, it was superb. For a time over the course of about three years, service and food became inconsistent. However, a bit over two years ago a new management team did take over, in addition to changing out the executive chef. Since that time, we've found the restaurant has returned to its former glory. Granted, part of our love for AP has to do with the fact that my wife and I first met there, had our first romantic Disney dinner together there, and wound up getting married at the Lodge a few years later (yep, used AP as our wedding reception dinner location). Though I recognize that our attachment is somewhat emotional in nature, there's no denying AP is usually a topnotch venue. Yes, it has off nights still, I'm certain--I don't know of any place that doesn't outside of V&A's--but it's a lovely place to dine and one where you can go with a good deal of confidence in knowing you'll have an excellent meal.
FOOD: Excellent overall. They used to have bison on the menu year round, did for as long as I've been going, until recently. I wouldn't be afraid to try any game meat they offer, however. The salmon is their signature dish and is usually perfectly prepared (dear god don't order it overcooked). Having lived in AK for four years, I will attest to Copper River salmon being a real treat--richer, firmer. The smoky mushroom bisque is still the best starter on the menu (though the braised short rib Bolognese is darn good, too, as is the charcuterie). As for sweets, while the berry cobbler has been there go-to dessert over the years, they changed the recipe a few years back to involve fewer berries and a denser, chewier crust. It's still a notable dessert, but the house made donuts with dipping sauces is actually a bit better.
WINE: Their wine list is focused on Northwest wines, i.e., Oregon and Washington. As a general rule, the reds from Oregon and whites from Washington are the way to go. Oregon has a superb reputation for Pinot Noirs, for example. Washington and Riesling go hand in hand, too.
SERVICE: Usually excellent. Often exceptional. Rarely below standard. Management is very responsive.
AMBIANCE: One of the (if not THE) romantic restaurants on property. The Lodge itself is beautiful, and that feeling extends to AP, as well. For one thing, AP is rarely crowded, so that helps. If you can get seated close to a window, the expanse of the courtyard/pool area, the Old Faithful geyser, and the lake are available to you. Unlike, say, CA Grill, you can actually hear your dinner mate if you're having a quieter conversation. After dinner, walking around the lush grounds of the Lodge is a must.
Artist Point is very good. Whether the menu, ambiance, and location appeal to you is a decision only you can make.
