Answer to the second question is yes, almost universally - swap it for anything sporting the purple DDP logo at the same location. (Be Our Guest does not support this because of the way drinks are served.)
I'm staying at WL later this month, and received the following info in an email from Disney:
We are pleased to share our latest addition, Geyser Point Pool Bar & Grill, will be open during your stay while Roaring Fork, our quick service food and beverage location, and Trout Pass Pool Bar will be closed for refurbishment. Please be aware of the alternative quick service dining options that will be available for your enjoyment:
Geyser Point Pool Bar & Grill will serve breakfast, lunch and dinner as well as specialty cocktails, beer and wine. The menu offers a variety of items, including hot breakfast entrees, a gourmet burger, sandwiches and salads. Kids' meals will also be available.
Territory Lounge is now offering a continental-style breakfast featuring gourmet coffees, pastries and a yogurt parfait.
It doesn't mention the dining plan, but I'm assuming you could use QS credits there.
Guests can expect to see an array of small-plate dishes on the menu including Shrimp on a Wire with Miso-Lime Vinaigrette, Togarashi, Shishito Peppers, and Chili-Aïoli. Also included on the menu is a Bison Burger with Tillamook Cheddar (another nod to the Pacific Northwest), a House-smoked Salmon BLT with Lemon-Caper Mayonnaise, and a Grilled Portobello with Zucchini, Roasted Red Peppers, and Tomato. Desserts include a Chocolate Brownie Mousse with Caramel Popcorn and Toasted Meringue and a house-made seasonal pie.
