Union An American Bistro

$5 martinis on Saturday. Anything off the menu is good. Service is excellent.

Their happy hour is amazing! Tons of choices and lots of variety. Highly recommend for a quick bite or an entire dinner 's worth of appetizers .

Locals know: best restaurant in Castle Rock. Fantastic happy hour (2-6 PM, M-F): glass of good vino for $2.75! Weds night any bottle of wine half-off. Try the pork chop - maybe the best ever.

Holy crap that was good! Shared several apps and they were freaking delicious! Looking forward to coming back to try everything!!

I enjoyed the Calamari strips & Lobster :-) delicately cooked n Tender to taste :-P Raspberry Margaritas hit the spot

Best Calamari I ever had, not like breaded and fried rubber bands that most places have, try the pork chops too.

Oh man! Too much good stuff here! Love the Lobster sliders and Tenderloin flat bread . Mmm!

The salads are awesome! Service is great! I've never had a bad experience here! :)

The Martinis are the best, oh and the Ty flatbread !

Burgers and fish are excellent

Love this place. Great happy hour .

I love the cookiebar desert ! Chocolate chip cookie with caramel sea salt gellato...yum.

Awesome place to eat if you are in Castle rock

Steak cut calamari is good especially with the remoulade !

Both the food and service are unbeatable.
