Let me start off by saying that this place is AMAZING! Brought my boyfriend here on his birthday and we both were completely in awe with their food. The chefs make the sushi right in front of you, so like others have already reviewed, it's definitely best to get a seat at the sushi bar where you can see all the live action. They serve you loads of sushi so you don't still feel hungry at the end of your meal, and they also ask you if you want extra if you can still fit in more in your stomach!
I didn't find it hard to get a seat at the sushi bar, and only made a reservation a few days in advance, but I would recommend making a reservations at least a week in advance.
It's a bit pricey, but worth every dollar - we also tried the plum sake which was a miss for my boyfriend, but I thought it was good! Not sure if I would get it again, as it tasted extremely watered down, but it was still nice to try.
Definitely give this place a try if you're in for the splurge! (Also, this place is very casual - no need to dress up)
