As promised previously. Thanks to all of those who had suggestions.
On our first night in town, we ate at Chimayo, where we had a wonderful meal with great service. The chile relleno was only so-so, but the soup sampler (which had all four soups the chef is known for) was superb. Clearly still jetlagged, I made the mistake of ordering spare ribs thinking I was ordering short ribs. Since I don't really like pork ribs, I gave away most to my husband, who in turn gave me some of his wonderful meal, the grilled buffalo flank steak. I don't even normally enjoy buffalo meat, but this was marvelous. It had a lot more flavor than most buffalo I've previously had, which probably had a lot to do with the wonderful sauce. Overall, even with my mistake, a wonderful meal.
On Thursday we ate at fireside dining at Deer Valley, which was a fun meal. The food was nowhere near on the same caliber (and the guys were disappointed that most of the food was being warmed by the fire as opposed to cooked in it) but it was pretty decent and we had great service. The waitress let my husband and I split the beer tasting (a great value with excellent beers at $16 for 3 tastes) and probably poured us close to 3/4 serving each as opposed to 1/2 serving. Definitely try the beer tasting if you go here! If you are not staying in Deer Valley, you will need to take a taxi or drive here, and a taxi ran $20 each way.
My husband and I ate in the bar (after becoming "members") at Easy Street Brasserie on Friday evening. Despite the fact that we were so tired we nearly fell into our food, it was great. We shared the burger and the smoked chicken fettucine. The fettucine was okay but the burger was fantastic -- lovely charred flavor, still medium rare, with excellent toppings and great fries. We returned with our friends for lunch on Monday and were somewhat disappointed with the burger on this go around. We also tried the flatbread which was okay and the french onion soup, which was pretty good. On our return visit our friends ordered the chocolate souffle which was huge and wonderful. We were disappointed with the milk chocolate banana crepes, which didn't taste like they had any chocolate in them but only caramel. The chef insisted they were chocolate, but I found the description misleading. They were still good, so we didn't wind up sending them back, but I was nonetheless disappointed.
Saturday brought a disaster trip to Mariposa. The food was on the whole very good, other than my friend's veal which she said was surprisingly tough (though the foix gras on top was quite good). The appetizers were all quite good (we samples most of them), and my husband's red deer was excellent.
The problem was the service. They had a few reasonably priced bottles on the wine list, but when we chose to order one (one of our favorite budget wines -- La Crema Pinot), we were treated as though we were lepers. Everybody else got red wine glasses at other tables; when I asked for one as opposed to the white wine glass already set on the table, the waitress looked at me like I was crazy. Our bread came out after our appetizers, and only after we asked for it. The kicker was dessert. We were there at the end of the evening... we wanted the dessert sampler, but one of the desserts was no longer available in "sample size." It was something that could have easily been cut down for us, but the waitress refused to do it (despite the fact that the kitchen would throw it out that night). We couldn't even voice our concerns to a manager because seeing as how we were there at the end of the night, there weren't any left. You can take the shuttle here (it runs once an hour after 6:30). Our cab home was only $13 from here as opposed to $20 from Fireside Dining (they are in different lodges).
On Sunday, we ate on the mountain for the first time (we generally skip lunch while skiing) at the Canyons. They have a sit-down restaurant mid-mountain that was pretty decent and a lot less busy than the lodges. Not cheap, but not bad for resort food.
Our evening's trip to Zoom was pretty inexpensive, but more or less a disaster all around. I can't even begin to go into how bad both the food and the service were. We had a reservation, so no wait for us, but based on the line, you would have thought they were giving food away.
Overall, my top picks would be Easy Street and Chimayo. I would go back to Fireside Dining as well, but maybe not the next time as it's sort of a one-time-needed experience.
