I loovvvee Fushimi! I've been about 3 or 4 times and have enjoyed every visit. There's quite a bit of seating inside considering how it looks a little small from the outside.
During my most recent visit, I came for their dinner AYCE. Basically, you are seated, and there is an ipad on the table where you choose all the food you could ever hope for! They used to have little paper slips to make you're order on, but it looks like they've upgraded to ipads, which makes ordering numerous times much more convenient!
The portion of each ordered itwm is a bit on the smaller side which in my opinion is a good thing since this method allows you to try a larer variety of foods, even ones you potentially may not enjoy.
One of my favourite things on their menu is their walnut shrimp, it's deep fried and covered in a lovely sweet sauce, I get soooo many orders of thia every time I come!
