Brunch Menu
Robert N.

Union has the potential to be great, but ends up being just okay. We sat on the patio and it was big with plenty of space and was clean. Our service was mediocre, with extremely long wait times between our server stopping by our table. We waited for way too long after we had clearly finished eating to be able to pay our bill, even after the hostess walked by and we asked her for to go boxes no one showed up. The food was good, but the menu reads like a culinary vanity project--each dish bloated with unnecessary ingredients that serve no purpose beyond justifying a price increase. Having some basic options would make it more appealing to visit frequently. The cost was just as bloated as the menu and neither my partner or I finished our dishes and while they looked great the they did not justify the price.

We met a friend here while traveling in CO. She offered up several suggestions and after looking at Yelp reviews, chose to meet her here. We sat out on the patio, which was beautiful. Castle Rock is exploding not only with housing but businesses including restaurants. We were so happy to land here! Their menu has a great variety of sandwiches, salads, flatbreads, and so much more. We started with an order of the calamari fried crispy which was served on top of the creamy remoulade. Oh my gosh...this is some of the best calamari we've ever had with a crunchy outer crust that was light and crispy. The calamari inside was tender and cooked well and the remoulade added the perfect dipping sauce. So flavorful and wonderful!!! I ordered the grilled 4 oz tenderloin salad which is made with mixed greens, tomatoes, onions, bacon, blue cheese and crispy potato strings. Everything is mixed with a yummy yet light blue cheese dressing. The meat was sliced thin and was so tender and juicy (I ordered it medium). The salad itself was fresh and found no slimy leaves as you sometimes do in mixed greens. Overall the salad is big and I wasn't able to finish it all but those crispy potato strings are the bomb! They added a great crunch to the salad. Wife had the Greek Flatbread, which was a great vegetarian dish with tomatoes, red onions, romaine, olives, pepperoncini, and a creamy dressing made with artichoke and spinach. She loved it! Said it was fresh and she liked the way the flatbread itself was soft and tasty. Our friend also ordered a flatbread, the Thai one and she said the peanut sauce they use is "the bomb"! It comes with chicken, cheese and what they call an Asian salad which had lots of diced veggies. We had to order dessert because they had coconut creme pie on the menu. Ok, so this is what creates my 5 star review! That pie...oh my gosh. First, the crust is light and tender and then the filling is beyond words to describe. It was huge, creamy, full of toasted coconut and was one of the best pieces of pie we've had! Seriously...it was so good! Overall a wonderful meal, a great experience, and service from Sydney was wonderful. She was attentive and helpful and had a great, friendly personality. Thanks, Sydney!!!

What a wonderful, quaint bistro in downtown Castle Rock. My husband and I were in town for the holidays and wanted to meet friends over lunch. Castle Rock was a great halfway point. Union An American Bistro had fabulous food and a cozy atmosphere that was quiet enough for us to visit and catch up. We started with some appetizers of marinated olives and Butternut Squash. Outstanding flavor, warm, and delightful. My husband had the Thai Chicken Flatbread. Perfect lunch portion. I shared it with him along with my order of Coconut Fried Chicken. Loved the shoestring fries that came with the sandwiches. Delicious. Our friends had the Brie Grilled Sandwich with salmon, a salad, and Adovado Spiced Shrimp. I didn't try their dishes but they raved over their offerings. Don't pass on dessert. The Coconut Cream Pie is heavenly. Add some coffee to round it out. Our server was pleasant and helpful and extremely patient while we visited and leisurely perused the menu. We will definitely keep this gem in the rotation for future visits and tell all our Colorado friends and family to stop in.

Cocktails

Truly, the only thing that I DIDN'T like here was the fact that there were too many parents who don't curb their children there. Toddlers and babies were just running amuck, and it didn't help that we were sat in the very middle of the restaurant. The cocktails and food were amazing and the service stellar, but it felt like being in a preschool! Does everyone in Castle Rock do the "soft parenting" thing?! I might not be back because of this.

I was with a group of five. We sat on the patio, which is super nice. The inside dining is nice as well. We all ordered different dishes and everything was amazing. I especially enjoyed my mussels! They were very delicious! I will definitely be going back.

We went here on a Friday and we couldn't eat meat due to Lent so they had lots of options. The Brie plate appetizer and calamari was a great combo and it made us full already. The salmon was great and just the right size. The tacos were flavorful but we had to take it home because we were full. The service was fast and the menu was great because they had happy hour as well as discounted appetizers because we had an early dinner. There was a dining area extending the restaurant but we opted for the area by the bar as that area had the discounted drinks and apps. The server was knowledgeable and kind and we really enjoyed ourselves.

Location (3 stars) On a main street but parking is limited. There is a parking garage connected to the building that the restaurant is in. It is tiny with sharp turns to access.

Service (5 stars) Staff have been a delight during each visit. Food (5 stars) House made chips are fire. Tried the brussels sprouts, pretzel & queso, chips guac and salsa (not feeling the salsa), french onion soup, jam it up, island style crab rangoon, short rib enchiladas, and the spicy peach. Everything mentioned except for the salsa was on point. Simply delicious. Cleanliness (5 stars) Nice restrooms

I don't know where "reviewer" Keven went four months ago, but both interior & exterior looked brand new, so his references about shabby furniture are confounding. What he described simply didn't exist. The waitstaff was attentive and polite, and each course arrived within a reasonable time. As for the food, it was excellent. We had an appetizer of baked Brie and prosciutto, that was served with a spicy peach reduction meant to be spread on the toast quarters that accompanied the dish. The pastas were all fresh and prepared al dente, which is the correct way to prepare pasta, and there were a variety of sauces available for those who might want to change up the menu selections. I have absolutely no idea what these folks were talking about when they mentioned specifics available on the menu that they found wanting. Reading their criticisms, It was like they went to a different establishment. Whatever the disconnect, there is no question that Danielle's is a cut above most restaurants and well worth the extra price. If one wants food that tastes like the old country, then one has to pay a bit more for the experience when here in the US.

Always great food, cocktails, service and setting. We recommend regularly to all who we know.read more

This review is based on my visit for lunch on 1/15/2026…read more Came in for lunch at 1:40ish and was sat rather quickly at the bar counter that faces the kitchen. Get my menu and everything seems normal, look it over make eye contact with a few of cooks and then decide on my food. After about 5ish minutes someone finally acknowledges me and I place my order, soup/sandwich and Dr Pepper. Around this same time, someone sits next to me at the same counter. Immediate hi from someone in the kitchen, let me find someone to take your order, the full red carpet. They place their order a few minutes later, and we are off to the races. We are now about 10 minutes from when I placed my order drink and soup comes. Cool, just going to wait for my sandwich but eat a few spoonfuls. Another 10ish minutes pass and I have now finished my cup of soup, still waiting on the sandwich. Here's where things take a turn, person next to me gets their order and lo and behold it looks like what I ordered soup/sandwich and some kind smoothie/shake thing. At this point it's almost 215 and my lunch hour is almost over and still no sandwich in sight. So I got up, paid for my had a cup of soup and Dr Pepper and went back to work. Thanks for helping me keep my calorie count low today Manna.

This is truly an elevated hospital dining experience. Most hospitals just have few selections for food but this restaurant has a full menu and wait staff. The food comes out fast and they are very friendly. Everything we tried was delicious. They have weekly menu options for a special burger and pizza of the week. You can also order ahead for pickup too which is a nice touch. If you're loved one is in the hospital this is a nice reprieve and escape from visiting the hospital. There is plenty of seating inside and if you take your food Togo there are outdoor areas to sit as well.

We stopped in for brunch and everything we ordered was really good, but the Breakfast Hangover Burger completely stole the show for me. A burger topped with smoked ham, an over easy egg, avocado, American cheese, jalapeños, fried onion straws, and sriracha aioli sounds like someone lost a bet and just kept adding ingredients. Somehow it all works perfectly. We also ordered the Monte Cristo, which was crispy, cheesy, and exactly what I want when I order a Monte Cristo. Another highlight weee the donuts.

As I have the past several times here, I went with the egg and carnitas tacos. I added a side of fresh fruit...both the eggs and fruit were very good. As the Benedict my wife loved is no longer on the menu, she had the avocado toast with eggs. She added a large size of the breakfast potatoes and was glad she did. While she liked the taste of the avocado toast, she was very disappointed in the small size of the portion. She wish she had more. One daughter had the Mardi Gras omelette for the first time. While she liked the flavor, the fact that the ham was a full slice (lunchmeat style), as opposed to chunks or cubes, was weird...and required cutting with a knife. The other daughter tried the quiche for the first time and loved it. It is one of the better quiches around. Coffee is very good as well. Service was fine for the most part.
