  • "Our first time here and no disappointments! Great food, exceptional service and a true local gem in downtown Castle Rock, Colorado."
    Dined on 4/11/2014
  • "Very accommodating and cheerful staff. The food though was hit and miss. While their signature pork chop was excellent and a delight the accompanying Cole slaw was watery and flavorless. Their take on Cajon pasta was bland any only contained two shrimp. The small plate Thai Flatbread was both tasty and generously portioned."

  • "What a treat! Mussels on the lunch menu with a succulent sauce and adequate baguettes to enjoy the full flavor. I have eaten mussels in Belgium, Denver - where many sauce choices are available but Union's mussels were the best - in flavor and texture. An extensive menu. Very friendly service too."

  • "Terrific meal with terrific service. The coconut cream pie was the BEST ever!!!"

  • "For dessert, order a bottle of the Boulevard Chocolate Ale."
    Dined on 3/28/2014
  • "The quality, quantity and variety of the selections was great Friday night, and the servers and other staff, as always, were friendly and welcoming. For the first time in a long time, we (party of 3) had to wait about 15 minutes past our 7 PM reservation time for a table that was of equal quality to what we had asked for through Open Table. Once seated (great corner table!), service was slow, yet unfailingly pleasant. This is our favorite Castle Rock restaurant and a single evening of uneven service cannot change that!"

  • "Great food as always...Stacey was cordial, personable and caring for our group of 7."
    Dined on 3/28/2014
  • "We had the special Spinach Salad - I didn't want the shrip and they easily substitutted chicken with no issues."
    Dined on 3/26/2014
  • "Only complaints were hi noise level and extremely poor lighting. Almost difficult to see what you were eating. Food and service were great."
    Dined on 3/22/2014
  • "We had a reservation and were seated as soon as we arrived. I overheard them telling people in front of us that there was a 35 min wait. Our waitress was awesome. She was super friendly and very knowledgeable about the food and drinks. My date went with her suggestions on ordering the special which was a shrimp and lasagna dish and I ordered the pork chop. Both were absolutely delicious. We tried two different martinis and both of them were good as well. For dessert, the waitress highly recommended the coconut cream pie and it was delicious as well. The place is pretty pricey, but you get what you pay for and it was totally worth it."

  • "My friends and I love going here on Sarurdays for $5 martini night. They are delicious! The food is good too!"

  • "It's my "go to" spot when I'm in Castle Rock! Great food and Service."
    Dined on 3/20/2014
  • "First, food was great, as usual. Our server also did a great job!!! Things to note that could be viewed as an opportunity: - Very loud in the lower dinning room, difficult to have a conversation. The bar was much better. - Reservation was for 8:30 but not sat until 9:10, I feel we may have been lost in the rush. No big deal but made it a very late evening with kids at home. We'll be back and bring friends"

  • "The double boned pork chop had outstanding flavor."
    Dined on 3/8/2014
  • "My GF and I hit this during restaurant week 2014 and were both very impressed! The service was impeccable and the food was out of this world. Some patrons reviewed that it was a little too dark for their liking, but having gone to several "romantic" type of restaurants, I really didn't find this to be out of the norm. The chef's signature dish - double pork chop, was cooked exquisitely and presented extremely well. The wine list was also extensive. Overall a great experience for a couple seeking a fine dining atmosphere!"

  • "The food and service were great. It was somewhat difficult to hear our friends across the table due to the noise level. We will still go for dinner but perhaps not on a Saturday night."
    Dined on 3/1/2014
  • "Every time we go to Union we love it! The food is delicious, the ambiance is welcoming, and the service is great! One of my other favorite things about Union is how consistent it is. It is always delicious! I highly recommend it!"

  • "We had an excellent dinner at Union! Our table was waiting for us at our reservation time, the staff was friendly and knowledgeable and the food was excellent! Great dining experience!"
    Dined on 2/22/2014
  • "Our first visit to Union was fine, but we didn't leave raving about it. The place is loud and too happy-hour-ish a crowd for us. The pork chops are very good; you can't go wrong with that pick. There are some interesting salad and sandwich offerings on the menu, but not many choices for main entrees. There's a large martini menu, but my Cosmo was so-so. We enjoyed very attentive service, however, and when I spilled my drink immediately after it was served, they mopped everything up and replaced it instantly."
    Dined on 2/22/2014
  • "On a previous visit I had a tuna salad which was excellent and was looking forward to a repeat experience this time the tuna did not seem to be as fresh. My friend had a waldorf salad that she had before and it was excellent.. I will visit again and will try the salad again and if the tuna is not up par I will try something else. Over all a great value...the Saturday martini special was excellant."

  • "EVERY time we have visited Union we are nothing but pleased, satisfied, actually...completely thrilled we went there! Excellent food quality & presentation with friendly/fun service. We haven't been disappointed...but if we were, I'm confident we could tell any employee and they would immediately resolve a situation."

  • "This was my second time dining at Union and I was really happy with the food each time. My husband's steak special was incredibly tender and flavorful and the thai flatbread is my favorite."
    Dined on 2/14/2014
  • "Enjoy consistency of food. Menu has been updated which is great. Love the peanut butter bites"
    Dined on 2/13/2014
  • "The service was very good, as was the food. The server was very pleasant and accommodating. The food was good, but not great. We began with the salmon tots, and had the Waldorf salad, blackened fish sandwich, and carrot cake for dessert. The only disappointment was that the restaurant was so cold that my companion had to wear her overcoat for the entire meal. Also, the only chocolate dessert was a peanut butter cup, and she is allergic to peanut butter, so, another chocolate dessert would have been nice. Also, it might have been that we ate a bit later in the evening and the french fries were not fresh. Carrot cake was moist and flavorful, and the fish was prepared quite nicely."
    Dined on 2/8/2014
  • "The food at Union is always fantastic, and there's always something new and delicious to try on the menu. The waitstaff is friendly, helpful, and energetic, and the prices are extremely reasonable for the amazing food."

  • "Exciting, vibrant atmosphere. Outstanding food. Feels like you're downtown Denver but you never had to leave hometown Castle Rock. We were there Friday evening, our reservation was helpful. Highly recommended..."
    Dined on 2/7/2014
  • "Great place to celebrate any occasion in a quiet private manner. As a family we wanted to have a low-key dinner with our son who was celebrating his birthday. The food was excellent - down to the last bite. Started with 3 wonderful small plates that were simply wonderful and well presented. The flavors were perfect especially the Thai flat bread. The salmon dish was done to perfection, the daily special could not have been better and my wife always loves the beef tenderloin. While the large plate menu is not long, it offers something for everyone. We have never failed to enjoy our dinners at the Union. By the way, the chocolate dessert is VERY rich - don't attempt to eat one by yourself."

  • "Big bar scene and typically loud. We did however go once on a snowy Saturday afternoon and it was absolutely delightful. Food is very good and martinis are fun drinks. One of our two "go-to" places in Castle Rock. Other one is sister Uniscali up the street."
    Dined on 1/29/2014
  • "We were meeting a couple from Denver so we picked Castle Rock due to it being a mid way point for us all. This place was highly reviewed so we went for it. No disappointment. The place was cute and trendy, Lively but we were able to converse with no issues.....this isnt a quiet place though. Food was exceptional and very reasonably priced. We will definitely return."
