Ai Sushi is an excellent place to go to for sushi platters if you're around Richmond Hill/Markham! I was on Yelp on a Saturday night looking for some quality places to get sushi takeout and stumbled upon this gem. They currently have a "Platter Series" deal going on and it's pretty worth it in my opinion. You can either get assorted sashimi, assorted rolls, or an assorted sashimi/sushi/roll mix. You can also get these if you choose to dine in as well - there are a few tables inside with a very casual atmosphere.
I opted for the assorted sashimi/sushi/roll mix because I enjoy the variety. Everything I got in my platter was just delicious! There were two of us, and we ordered the 60pcs for $40. While we were able to finish everything, we had to kind of force ourselves near the end, so I'd recommend getting only 40pcs ($30) for two people unless you're SUPER hungry. There was a fair share of sashimi, sushi, and rolls - all items were fresh and great quality so no complaints there.
I would definitely come back for another platter! This place has some of the deals I've seen in the area.
