  • The Belgian street food style cafe brings us back in from the cold, or the heat, with a cute little cafe specializing in all manner of pommes frites w/ a wide range of mayonaise-based dipping sauces.
  • Not bad , good sauces but over priced and small cartons for sauces , get pork belly with your fries
  • As per the mayor's instructions, get a lige waffle with both caramel and berry sauces on it. Voila! Instant heaven!
  • The poutine is legit, have no fear
  • Satisfy your late-night cravings with an order of these Belgian-style fries or waffles. If you go for fries, add a savory sauce on the side - the truffle ketchup is one of our faves.
  • As a former Montrealer, I can say the poutine rivals some of the best I've had.
  • Seriously, get the Frikandel. Seriously good!
  • The sauce sizes are generous so order a few and take home the extra to put on sandwiches or ur fav foods. So good!
  • delicious liege waffles
  • Try the Liege Waffles - Amazing. Authentic just like in Belgium.
  • They have a multitude of dipping sauces.
  • Great beer selection.
  • Everything is amazing! Green moster is a great spicy sauce, but the Chedder duvel is to die for. Best heart attack you will ever have
  • Try the vampire slayer (roasted garlic & mayo) sauce!
  • Get the Cheddar Duvel sauce. You won't regret it!
  • We tried fries with chipotle sauce and the sauce with sour cream I forget it's name. Also the mushroom sandwich all delicious
  • Great food with great price! The staff is very friendly. I've been going there since the 1st year they opened and I'm glad that they've expanded the menu even more - way more creative too!
  • I love Saus. MAKE SURE YOU TRY THE SAUCES! ALL OF THEM. Their beer selection is great. Try their poutine and enjoy a Frik.
  • Everything is awesome. Seriously!!
  • Great selection of Belgian beers and frites
