They've decorated the place since I visited last march. At that time, I felt dissatisfied because the food seemed a bit mediocre... I felt that it just didn't compare to other Japanese restaurants (even though the owner offered great hospitality and I wanted to like the food as much as I liked the service).
HOWEVER, that was last march. My opinion on the restaurant has changed since then. I remember having Japanese takeout at a friend's house in the neighborhood a few months ago and thinking "Wow! The sushi tastes so good and the seaweed salad is amazing!" and honestly, I was pleasantly surprised when they told me it was Qi Sushi.
I'm really glad that their food quality improved - it's so nice to have such a convenient little spot to eat at in the neighborhood. They offer you a lot of food too! They're really generous in portions and I highly suggest getting the sushi combos because it fills you right up. It's a nice cozy spot to be at with your friends, even though the restaurant is pretty small.
When I was there, a lot of people was coming in to get take out. So you can tell this place is gaining a lot of popularity with the locals.
Overall, I think people (like me) shouldn't be quick to judge newer restaurants because there's always room for improvement. When the waiter comes by and asks you how you like the food, the best thing to do is to be honest and give constructive criticism so they can make better changes (if they have to).
But anywho, you're getting good value for your money. I say give this place a chance! I think you'll like it.
