Unique cocktail bars / casual bars downtown Calgary?

My sister is visiting me in Calgary for her 18th birthday! She requested a "chill bar crawl". I don't go out much so I need recommendations. Neither of us want to go to clubs or really loud bars. I would love to take her to unique/themed cocktail bars with cool drinks! Downtown/17th ave would be best as we'd like to walk in between. Thank you in advance!!
