Located in the Distillery District, the Ontario Spring Water Sake company distillery, as you might imagine, makes sake.
This is the first good sake I've ever had. The bar is small, 7 seats total, and sells sake on-premise in bottles as well as at the counter. The sake is smooth, flavorful, and in my opinion quite good.
When you walk in you might think that you walked in through the wrong door. You didn't. It's a true hole in the wall experience.
The drinks are very well priced and they also sell sake tasting sets (cups and such) at the bar.
If you're a tourist or just happen to be in the area and want to warm up for a minute, I highly recommend stopping by.
