I have never been to Ristorante del Lago at the Broadmoor, but generally speaking the Broadmoor is nice, but overpriced (obviously not as much of an issue if someone else is paying). If you have the ability to suggest something else at the Broadmoor, the Summit has a really solid menu, though I would assume the vibe and both to be fairly standard "nice american restaurant" vibe.
The Rabbit Hole is a solid choice, their food is good and their cocktail menu is strong. Last time I was there I had a Rabbit meatloaf and their version of an old fashioned which were both really good. The vibe is definitely unique as the restaurant is underground and they play up the carved out of stone thing. It does not feel like you are in the middle of the city when you are down there.
If you are open to other suggestions I would suggest checking out Margarita at Pine Creek, it is a very unique restaurant and the food is really good. I don't remember their beer/liquor being any good but the wine list is solid.
One brewery in town is a tough question.
As much as it pains me to admit it, Trinity is still the best brewery in town in terms of putting out quality beer. I have not given any money to trinity in the last year and a half however due to the head brewer Jason Yester's comments insulting the entire town because he got third in a local poll

Jason Yester is a ****** canoe of the first degree and is the exact opposite of most craft brewers I have met. One day a couple years ago I was there during the afternoon and they were clearly not busy. He and an assistant brewer were performing a mashing experiment at the bar, they had a couple of plastic tubs of different grains that were steeping in water and I asked them a simple question about what they were doing. Yester totally blew me off and didn't even bother to answer my question. With all that said, they still make some really good beer.
My favorite brewery to visit is Phantom Canyon downtown. Their beers aren't crazy in any particular way but they typically have one or two beers on cask and brew a lot of quality stuff, often with at least one historical recipe on tap at any given time. Their second floor has plenty of pool tables, darts and a nice patio if the weather is warm.
