Downtown Castle Rock Bistro

The selection of "small plates" is excellent and the food is delicious. We love the mussels with chorizo. Lunch is an especially good time on Wednesdays with half price wine by the bottle. Happy Hour is a great time. Music can be too loud at times and parking can be tight.

I'd prefer not to give a bad review unless its deserved. If one opens a restaurant and serves unfresh seafood then Im going to warn others from chosing that particular dish. I can't comment, much, on the rest of their menu but my order was the worse Ive ever had anywhere worldwide and yes Im well traveled. To serve a... More

The Union reminded me of the tv show Cheers, friendly, fun and neighborhood atmosphere. The food menu choices are outstanding but then there's the martini menu, oh my !! We tried the smoked salmon dip outstanding, then a Salmon salad for me and it was delicious. Carrot cake waffle to end, make sure to split this, it's huge. Great staff,... More

Looking for a quick bite just after a noon wedding. Found Union Bistro and brought our group of 7 people in. Quite a variation in diet needs and yet this small establishment was able to accomdate us all. From an easy hamburger to a Thai gluten-free Flatbread, it was all around raves for the tasty fare and efficient staff. They... More

Place is clean, food is good and service is great. Ladies bring a jacket the inside dining is very cold. The hostess was all over checking that our meal was good and that we were ok with everything. Parking can be located a block east of the restaurant in a free lot so don't worry if the 10 or so... More

Our friends talked about how wonderful the appetizers were, so we took a date night and went there with them. It was good. The salmon stack was delicious. The calamari was good. Different than we've had before, but good. The mussels were ok. We like Jack Quinn's better. But the homemade peanut butter cup was amazing! Just a couple of... More

The food here is truly amazing have had over half their menu, haven't found anything I didn't rave over and that's after having some of the best Mussels, calamari, Irish Spring Rolls, etc............ Mark is the king of Martini's and has made it hard to have a favorite. This place is a jewel, only hope to keep it a Castle... More

We had a lovely lunch here with our family. It was a nice place to meet up for a nice lunch. This place is good if you have any allergies. I have problems with gluten and their gluten-free flat bread is amazing! You can't even tell it's gluten-free! I highly recommend it. Their salads are huge, way more than you... More

When I want to eat somewhere a little more on the "finer" side, Union is our go to. Excellent food, although it is a very loud dining room and restaurant. Clearly that is not keeping me from going--their beef tenderloin is luscious and keeps me going back. For couples, friends, double-dates...I recommend this place. A little pricey to bring the...
