Just an FYI that Jackson Hole (and I guess all of Wyoming, if there are other "destinations" other than Jackson and Yellowstone) is BYO Friendly.

On a return trip last week we made reservations at several restaurants well in advance, inquired about BYO and ended up bringing several bottles on our roadtrip through the state.

Recommended Jackson restaurants -

Snake River Griill - Have dined here at least three times over the years. Located right on the square downtown, the food is solid, a bit noisy but recommended nonetheless. We never found a "real" manager or sommelier with whom we could share a sample of our wine and were charged $20 corkage.

The Granary - Located at Spring Creek Ranch / Amangani on a butte over the town. We stayed at Spring Creek before and during this trip, but it was our first dinner here. Outstanding and unobstructed view of the Tetons from their floor-to-ceiling windows. Very good food, shared a sample of our wine with the staff and were not charged corkage, which I believe is $15 otherwise.

Wild Sage (at the Rusty Parrot Lodge) - Three blocks off the square downtown, this establishment has only six tables surrounding its open-air kitchen and was the restaurant of the trip. Mussels and Crabcakes were among the finest we've had anywhere. Elk tenderloin and wild salmon special were also outstanding. We had a little leftover Pax Lauterbach Hill from the prior night as well as a bottle of
Quilceda that we shared with the Chef and waiter, and corkage was again waived. This is a MUST-VISIT restaurant, even if you're staying at the Mountain resort 10 or so miles from downtown.

During other visits we've stayed and dined at Jenny Lake Lodge in Grand Teton Park. The most beautiful spot in the world in IMHO, and without a doubt the finest dining you'll ever find in any National Park.

Great info. The Wild Sage sounds great. Also the Granary. I've stayed at Spring Creek Ranch 2 or 3 times and I never even knew they had a restaurant

Our next trip to the area we are staying in a rustic cabin in the Lamar Valley in the NE corner of Yellowstone. No good restaurants, but good views of wolves

The Granary is in a building at the southern end of the pond where some of the rooms are located. I've always stayed in one of the larger condo-like rooms elsewhere on the property. As for Yellowstone, yes, you're screwed. We spent two nights in W Yellowstone (the Hibernation Station is a strong recommend for lodging) but found no decent food. Even our 14 year-old was joking about it, accustomed as he's become to linen napkins in restaurants. Should be beautiful. Enjoy!!

I just spent a couple of days in Jackson Hole after elk hunting near Salmon, Idaho. Jackson is pretty much shut down this time of year, post summer/pre ski season so pickins were slim with most restaurants closed or only open weekends. Hotels are dirt cheap though, clean simple room <$40.
Rondevous Bistro- I ate at the bar, didn't even enter the dining room. Good service, friendly patrons, decent menu, wine list...ho-hum, but not terrible. Had a baked quail over spinach greens appetizer and venison tenderloin main course with fresh kumamoto (sp?) oysters for desert . Wine was a '98 Blason de L'Evangile, $78 off the list (which along with '98 Chateau Gazin, and '99 Torbreck 'The Factor' and '99 and '02 'Run Rig' seems to be everywhere in JH). All food was well prepared, tasty, well served, and decently priced. Would eat there again.
Silver Dollar Bar and Grill (Wort Hotel)
Had the $34 18oz, prime, t-bone and garlic mashed potatoes. Prime my ass. Outdated decor. Not worth the coin by any stretch of the imagination. Wine list average. Not recomended.
I wanted to eat at the Granary, but chose the Wort instead due to proximity .
