We went for sushi last night to Oishii Sushi. We had read some of the reviews about Oishii Sushi, saw that they were good, and decided to buy a Groupon for it. The restaurant itself was quite lovely with its side open to let in a calming breeze. It is also in a good location with plenty of people walking outside and with it being near to Mount Royal.

We found that the sushi was OK, but we must confess to being a little disappointed given the other positive reviews (some of the other reviews say ""in a city not known for good sushi"", but we must uphold all sushi restaurants to the same universal standard regardless of whether they're in Japan or Nunavut). My main issue with the sushi is that a few pieces fell apart when we picked them up with the chopsticks, indicating that the sticky rice was perhaps not as sticky as it should have been. Also, I'm a bit used to some sushi pieces having a hint of wasabi inside for an extra little ""zing"", but no such zing was to be found inside these pieces. Some of them tasted a little plain, perhaps not being as fresh as we would have hoped for. One of the shrimp tempura pieces was somewhat strangely not fully connected. Finally, the prices were not as good as we would have hoped for given that the sushi didn't measure up to our universal standard.

In summary, we will be looking for other sushi restaurants in Montreal, but we might find ourselves back at Oishii Sushi if we do not find better ones.

While the food here is good, there are a number of reasons why I can't recommend it to my friends.

The inside is cramped and aged and while I have no problems with hole in the wall style restaurants, this is not an excuse to have an unclean interior which looks like it hasn't been cared for in many years. In addition to this the owners of this franchise look to nickel and dime you in every conceivable way including charging for tap water, charging for soda refills, and charging you $3 if you want to use a debit card. Not only this, but if you want to get your sandwich to go they'll charge you extra for fries, which are normally included as a side if you eat in. A typical sandwich will run you about $8 with no drink.

One time while I stood in line waiting for a sandwich, the man who appeared to be the owner started complaining to his employees that whoever cut the portobello mushrooms that day had made them too thick, which was ""costing him money.""

Nothing puts a bad taste in your mouth like getting ripped off.

I broke my dental bridge in 2010 in a work comp accident. I came to see Dr. Hourouni after doing my due diligence. Top of class USC blah, blah. After being fitted with the bridge, I knew I had an infection from poor fit at the margin. He saw me and ground down my natural teeth and the bridge. Still no improvement. I called his office and got the office manager. She told me to ""rinse with salt water"". Long story short... I had gangrene under the bridge, a subsequent bone infection, had a PICC line for 2 months and almost died from meningitis. I have lost 6 teeth. It is now 2015. I am still miserable and will be going to get 6 implanted teeth. My pain is controlled with narcotics and I have a healthy resentment. Dr. Hourouni, you are a joke of a doctor, your shoddy work is exceeded only by your glossy pictures and ego. Thank you for ruining my smile and my health.
