It's such a great place to meet a friend. The food is really good. My favorite is the Asian Salad with the blackened salmon. Wow! So good! The service is friendly. They have a specials board up on the wall. It's just so cozy and nice. I love to go there. read more

Great local bar with tasty food. Monday night during the summer they have a car show where they Offer specials on burgers and beer. Great place to unwind in a small town with friendly people. read more

Clasen's Tavern - No complaints about quantity, quality or price. - Piano Bars Near Me - Union, Illinois

This is the perfect bar / tavern to relax and have a drink and some food after visiting the Illinois Railway Museum. The bar is just beautiful and when you enter you feel like you just stepped back in time to the prohibition days. The bar definitely has history and you can feel it. Even if you are just passing by and the crowd is definitely local with regulars you will feel welcomed. Staff is friendly and effective. The menu is what you would expect for bar food: burgers, wraps, salads... so plenty of choices for everyone and it was good and well priced. In a nutshell it was a perfect experience and I wish more towns would have a bar of that quality. read more

Fun lively tavern with decent and reasonably priced food. Love The atmosphere and friendly service. The chicken wings were good but the fries were a tad soggy. The shrimp were hot and tasty but the cocktail sauce had the consistency of jello. The tartar sauce was good. Tons of locals - it has a very welcoming atmosphere. The outdoor patio has nice seating and the interior of the restaurant has beautiful paneling and booth seating as well as high top seating. Will try the burgers next time - people say that is what this place does best. Bartender was also our waitress and despite serving a large crowd at the bar - she was very attentive. read more

Classic old tavern that has outstanding made to order burgers and friendly staff. The did recently remodel by incorporating some knew booths. Don't drive through Union without experiencing their burgers! read more

Nice neighborhood place. Check out events and they may be having. Good food, drinks.

Outstanding. Great food, comfortable and relaxed atmosphere.

The food is great and the drinks are cold. Their outside beer-garden is nice in the summer-time!

Ever since going out to the IL Train Museum since 2020 this place is the place to go when eating at the train museum. The food is great! I enjoy the cowboy burger with bacon and mayo added in there as well with fries or tots and it's worth coming to every time I come out to IRM or in Union IL. read more

Great food, love the burgers, and busy in the summer with outside seating and music. Staff friendly and the service is pretty quick. The seating inside consists mainly of tall tables which is so popular but not everyone likes those and they are not exactly handy for challenged people. Thus the 4 star rating. read more

We went to this bar this weekend in hopes of sitting in the beer garden, unfortunately the weather prevented that from happening. We sat inside and had the burgers and they were very good! We checked out the beer garden on the way out and it was very nice. We will be going back again! Very comfortable feel and a neighborhood place to go. read more

Wow...great food! We stopped here based on the reviews about the help and food. It sounded like it was going to be a great experience I'm just going to boast about the food Server was really friendly to people she knew at the bar. Sad, because I would have rated this a 5 based on food Sad how not friendly (and I'm being kind) help can change you image of a place read more

Awesome bar! Love riding my bike here to slake my thirst with a few drafts in the summer. Food is good and special events and live entertainment just add to the vibe. read more

Awesome food and service! First time in. Such a great atmosphere. Loved the patio! So quaint. Will definitely be back!

Ahhhhhh oldest and best wateringhole around. This place belongs in the untamed wild west. Where else can you find an "original" 1898 Baby Grand keyboard hanging on the wall. Story has it William Clasen opened the bar in 1900. It is truly the oldest tavern/bar in McHenry County. The building inside is as it was over a hundred years ago! It is a time warp when you walk in starting with the old time creeky aluminum screen door. The food is absolutely excellent. From appetizers of cheese bites to the crispiest wings around to sandwiches and burgers you will NOT be disappointed nor will you leave hungry. My heart of hearts wants me to leave 5 stars. Now comes the but....... Clasens was recently bought from the original owners. And with new owners comes price changes. And it really is a shame. We went for appetizers (we shared one), two burgers and a four or five beers. The bill was over one hundred dollars! $100 for beer and burgers. This is a dive bar. Nostalgic and lovely but it is still a dive bar. If I'm going to spend $100 on dinner and drinks this wouldn't be my first choice. It's so sad that they ruined this little piece of history, a gathering spot for locals and farmers alike. This is sacred ground with a very expensive price tag attached so bring your wallet with. read more

My new little gem!! Great little bar off the beaten path in Union. Situated in nice old building (from 1900) brimming with history. Love the (what looks to be original) nostalgic - turn of the century decor. Complete with baby grand piano circa 1898! Perfect bar ambiance. Very comfortable inside. Nice sized bar staffed with friendly bartenders. This is our second time at this bar and first time we ordered food. We ordered a Mac n cheese bites for an appetizer and they were delicious. For dinner we had the half pound burger which was delicious as well. Their website claims the meat is fresh never frozen and triple ground. I believe it. The patty was hand packed, cooked and seasoned to perfection. They have an impressive menu. Be sure to visit their website to familiarize yourself. There is something for everyone including a veggie burger. Drinks are reasonably priced and served nice and cold. I ordered a dirty martini that was made to perfection. I also had a couple Bud Lights which was served nice and cold. This little bar has everything I look for in a neighborhood bar. They also have an outdoor patio if you would like to sit outside but you would be missing out on fantastic atmosphere the inside has to offer. They have special events such as live bands and meat raffles and this info can be found on their website. Definitely worth a try. read more

Have lived in the area for a couple of years and friend finally convinced me to check this place out. Waitress/bartender isn't very friendly and doesn't have a great attitude with regular patrons if you're not a reoccurring local or buying her a shot. Food was good but I wouldn't be back unless my friend really wanted to eat here again. read more

Wanted to take a drive out a farm area to have lunch. Found this place on Yelp. Friendly place, staff & owner very nice. We always dine in momma poppa restaurants. We had the the shrimp special & I had the homemade burger. The red clam soup was also good. We met the great grandson of the original owners from the 1900's that was so n for a drink. How often do you meet a great grandson from an establishment that started in the 1900's. Spoke with the nice owner & he told us that they have pig roast, LOBSTER bakes, & much more through out the year. read more

We found this place (way off the beaten path for us) It's a super old bar with awesome food and drinks. They always have a food special and just opened an outdoor patio. What else do you need? Pleanty of parking and there is always a few classic cars or bikes parked up front. The owner is always here walking around and hanging out with the guests. This place is 30 mins from our house but we would drive an hour for the experience. Oh did I mention that dogs are allowed on the outside patio? Just awesome! read more

An absolute gem in the cornfields! Not really far away from surrounding towns, but far enough that you feel like you've escaped the everyday bustle. Oldest bar in Mchenry County holds the tradition of never closing even during prohibition I've heard. This bar has as many folk tales as it does cold beer and good patrons. The wine selection is excellent and the kitchen produces some amazing meals. Inside enjoy the nice a/c and outside the cozy patio. I highly recommend this place to locals and out of towners. read more

I can't get enough of this place. After receiving a text today about a free pig roast I had to stop in. Since I was there last they have added an outdoor beer garden for your enjoyment. As usual the food was most excellent. It's a small place in a small town with big values. Yes I will be back! read more

Great looking interior. They have plexiglass between the booths and the bartender/waitress kept her distance. I had the American burger with cheese and bacon. It was excellent. My hubby had the buffalo chicken wrap. He liked it; it was spicy but not too spicy. Our meals came with chips but we ordered a basket of fries as the appetizer. They came out the same time as our meals but that was OK. They were the large crinkly kind and they were very hot which we enjoyed. No draft beer and no moscato. Only here in town for the weekend, but if I lived around here I would certainly go back. read more

This place's secret- cilantro. This food is amazing and the atmosphere is rather comfortable. The service was great and the only negative aspect is the place definitely isn't quiet. Also, no pianos. Would definitely return next time in the area. read more

The steak sandwiches are great, and so is the atmosphere. Even though they were a little short-handed when we stopped in, service was still good and friendly. read more

Great little place for a burger and drink. Staff and the locals are friendly and the service is quick. We go there whenever we are in the area. read more

A top place for food, drinks and just to hang out. Have never had a bad meal or experience.

Enough about the whine, I mean wine, already. Order a PBR and a burger and STFU! Seriously, It's not that kind of place. If I want a burger almost as good as I make at home I go here, nowhere else, only here. read more

Didn't enjoy my burnt burger. The burgers are usually great but not today's. Please watch them better.

It sounds like a small thing, but this was hands down the best turkey wrap I've ever had. Full of smokey flavor, that was tasty. A lot of components to the fish tacos, but my mouth liked them too. Stopped by for lunch on a Friday, tavern was fairly quiet. Quite a few guests, but not too loud. Staff was very friendly. If I lived here I'd be a frequent customer! read more

One of the all time best small town taverns, cold beer, good company and the best burger in the county. Bartenders are always friendly and they appear to know everybody by name when you walk in the door. If you get a chance to stop I suggest you do so..... cool place to hang out. read more

Good out of the way neighborhood bar and grill. Great burgers and drinks. Stop by and enjoy!
