I'll start by saying that the quality of food here is acceptable. In fact, even more than acceptable when considering that the lunch all you can eat is $13.
The fact is that this restaurant's problems don't really come from the food itself. Rather, the lack thereof. Nearly every single time I come here I have to jump through hoops to get what I want.
The servers are incredibly unfriendly starting from our beginning "welcome". The staff is incredibly cold and distant for the entire experience. Simply no frills--they are here to get you in and get you out; there are no attempts at being polite or even remotely personable.
Sometimes I don't mind this as long as the service itself is speedy and accurate. Unfortunately Mika has neither of these qualities. As you continue to eat, they become slower and slower with delivering your food. It's also incredibly likely that they will simply not give you several of your items (I assume this is because they presume their average customers are uninformed/ignorant and that the missing food will simply go unnoticed). Thankfully I have decent knowledge of Japanese foods and their English equivalents, so I will notice when I do not receive something.
They have a habit of deciding when THEY think you've had enough to eat. After a certain point, if you want to order more, they will give you a hard time when you try to put through your next order sheet. They will reluctantly accept your order but you can be guaranteed that the service will be dreadfully slow and your order will likely come incomplete.
I had garbage and empty plates pile up gradually as my meal went on. The waitress did not care to take any of these things away even when she brought us food. You will not be approached regarding drink refills, and you can bet that you'll have a hard time approaching them because they do all they can to avoid you unless they are bringing you food. No one came to check on us to see how we were doing. I got so thirsty at one point that I had to go the bathroom and drink their tap water.
Another thing. None of our sushi came with wasabi, which is unheard of for a sushi restaurant.
In short: you come here and pay the relatively low prices. You eat the decent food while trudging through the bare minimum service. If you are here purely for the food, there are many many better alternatives in Oakville. If you are here even remotely for good service, you are wasting your time. If you are here solely for a low cost meal, then you shouldn't have an issue.
