I tried the tempura udon, futomaki and inari at Sushi Maido in the Annex last night. I’d asked about the sushi places in the Annex 5 or 6 years ago, and jennabeans on CH had recommended Sushi Maido over the others. It was quite full around 9 pm on a Friday, and the staff were friendly.
Confession time 
I used to go to Sushi on Bloor, New Gen and Sushi Inn (in Yorkville, but the same kind of sushi place) from around 2002-2010 fairly frequently, but I haven’t been to any of the Annex places between Spadina and Bathurst in the last decade.
I also visited Sushi Island AYCE on College St at least once. I became a bit fussier about sushi around 2010, and usually chose Japango or Yuzu No Hana when downtown.
I liked what I ordered at Sushi Maido, and the prices were reasonable. I was in the mood for udon.
Re: the futomaki, it was fine. I like the sushi rice a little more at Akai at Harbord and Borden https://instagram.com/akai.sushi.toronto , which is probably a little pricier.
I almost walked down to Omai last night, which I like a lot, but I was craving udon and wanted to order online.
If anyone has a recommendation for takeout udon, let me know! I do like the creamy non-traditional mushroom udon at Planta!
