We did Denver/CO Springs last August. The Fort is a fun place to eat and the food is good. Red Rocks is a must do.
I looked on a travel website for restaurant recommendations in Denver and Twin Peaks got wonderful reviews. We went there for lunch...me, DH, DD10 and DD14. Little did I know it was a Hooters-type restaurant! After we had a good laugh, we did enjoy our meal. They even had kid's menus.
Hidee Gold Mine is a lot of fun! I think it's closer to CO Springs though.
If you do CO Springs, visit The Broadmoor. It's a beautiful resort with lots of good food options. There's a restaurant at Seven Falls too that is good.
If you have time to do whitewater rafting, I'd recommend Echo Canyon River Expeditions. Pikes Peak Cog Railway is fun too!
Good to know about Twin Peaks

Although I could tease one of my nephews with it, when he was 5/6/7 (somewhere in there) he had a thing for Hooters... I forget what he liked on the menu but he always wanted to go to hooters for dinner. We were out in Vegas during this phase and on the way back from the Hoover Dam he spotted the Hooters Hotel/Casino and you could just tell he was floored. He said 'mommy, when we come back we have to stay there!' We all got a good laugh on that one, even mom.
Now that he's getting to be a teenager one day soon it will all come back to tease him with it.
Now the Broadmoor, what can I say? That's just spectacular, if we ever get back I'm pretty sure that's where hubby is staying

If I show him this trip he's going to be vastly disappointed in our current accommodations
And I would totally love to try the whitewater rafting, I'm going to keep the Echo Canyon River Expeditions in my cap for a future trip. We have decided we don't need to be in anyone's wedding album in casts so I'm supposed to be good (read, tame) about our outdoor adventures. But one day it will happen, that's how I want to see the Grand Canyon... I think I'm alone on that one, hubby said he'd wave from the top...
Casa Bonita is famous and made even more infamous by South Park. The food stinks but its a local legend. White Fence Farm in Littleton is a favorite...great chicken and lots for kids to do. Denver is known for green chili! Beau Jo's pizza is great...there are a few locations around with the original in Idaho Springs. I personally recommend Tocabe for Native American fry bread tacos. There is a location in the Highlands and another in South Denver. Its like Chipotle only with Native American ingredients.
Estes Park and Rocky Mountain National Park are very close to Denver. I highly recommend them!

Green chili, check! Will be sure to check that out. I think I saw Tocabe in the list for Taste of Colorado festival and that seemed like one of the few things local that I'd want to try. So may as well just stop by the restaurant, it's very intriguing.
We went to the Buckhorn Exchange last time we visited. My husband had some wild meat and I just had beef filet. We also had rattlesnake queso. The queso was good. My husband liked his but mine was seasoned with so much pepper and was overcooked. The dinner salads were delicious
We LOVE going to D Bar Restaurant. We went the first time for lunch and loved it so much we went back the next day for brunch
D Bar is amazing! For those who don't know, its Keeghan Gerhard from Food Network's restaurant that specializes in desserts. The food is outstanding and I've seen Chef Keeghan there several times.

Sold, D Bar it is. I went to the website and everything in the video looked amazing.
You've gotten some great advice on things to do in Denver. For me, though, what Denver is, is the closest major airport to the Rocky Mountains. It's a perfectly nice city, but what is really special to me are the mountains. If it were me, if I could manage it time wise, I'd head up to Estes Park, stay there and two nights / two days, and visit Rocky Mountain National Park. I'd do the wonderful Trial Ridge Road drive, stopping at all the outlooks on one of the days. I'd hike Emerald Lake from the Bear Lake trailhead on the other and after that head back to Denver.
It takes about two hours to get to Estes Park/RMNP from Denver. Those alpine lakes with the mountains and all the wildlife are just so cool.
OK that's multiple votes for the RMNP and I think that was on our list to research anyway. So, my dumb question for the night, is the Trail Ridge Road drive all by car with pull offs for the outlooks? Hubby saw a video for Mt Etna (the highest paved road in the America... whoo

) and thought that'd be a neat drive up for the view, but that kinda seems like all that's there is - the scary drive up, park, view, scary drive back down. And since it's out of the way it's still 1.5 hours one way from Denver. If we can do a drive through RMNP and get similar or better views then that seems to be the better use of time, yeah?
