howmanypeopleareon - The "Doors Open Winnipeg" event takes place next weekend. If you google the website, you can see the different historic and unique buildings, etc. that will be featured. While it's not a bar or brewery, Across the Board Game Cafe might suit you. Speakeasy - The Basement Winnipeg bills itself that way. They have a burlesque show scheduled for next Friday night. Ichiban Restaurant will be fun. Enjoy. There are many genuine ethnic restaurants in Winnipeg for you to explore also. While it will be a long weekend for you, it will not be here. This current weekend is the Victoria Day long weekend in Canada. Monday will be a normal work day for citizens of Winnipeg. You shouldn't have any trouble finding a yoga studio that's open that day.

If you have any interest in exploring historical venues, museums, art galleries, planetarium, there's no shortage of places in Winnipeg. You mentioned 'places with unique design'. I highly recommend the Canadian Museum for Human Rights at The Forks. You can spend several hours walking around The Forks market and surrounding area at the junction of the Red and Assiniboine Rivers.
