Change your fry grease yearly?....fries were brown, burger was sloppy and looked cheap. Used to be good when they opened but it's gone downhill...and not a cheap meal so very disappointed.

Staff was very pleasant, food was not bad. Slight issue with the shake machine, but the server made it right. We did have to wipe down our table before eating, which is annoying, but not a huge deal. Portions were large.

After many people describing how good Union Burger is, my family and I decided to stop on the way home from Niagara Falls. We were terribly disappointed by this filthy restaurant which was over priced and served burgers so greasy that they were slipping out of our hands. Not one table was clean when we entered and the server behind... More

It's hard to find Burger & Beer specials in Canada unless you go to a pub. UB is the exception. They also have great milkshakes & fountain drinks. Great gourmet burger combos come with fries, sweet potato fries, poutine or onion rings. They even have malt vinegar to top your fries. Good inexpensive family eatery. Better than average fast food... More

The only employees were a couple of young ladies..One serving and one cooking. Surprisingly I was the only customer on a Saturday night. The ladies were friendly, polite and described my options as it was my first visit ever. Maybe it was because I was the only guest but the attention to detail was superb. - I ordered a Bourbon...

As in "Don't go there!!!". If you think you'll get the burger that is pictured with this review, you will be sadly mistaken. First, if you get fries be prepared to get little burnt end pieces and not very many of them. What's so difficult in frying fries?! And why not fill the paper cup?! It certainly defeated Union Burger.... More

Perhaps it was my order or perhaps this is the standard. As mentioned in title this review is based on my 1st and only visit this far to this establishment. Order: Peppercorn goat cheese burger with a small poutine and Corona to drink. Bonus for offering beer. Result: Approximate wait time 5-10 minutes. Bun seemed stale, burger lacked peppercorn and...

UB is the perfect union. Fresh burgers and hand cut fries. Flavour and variety. Freshness and fun. And... UB is an attitude. Engaging. Memorable. And Eclectic.
