Whoa, Blue Star just happened to me. See, we were just poking our heads in to see what this place was about about. Immediately the host (owner?)--a very tall solidly built young man--took charge of the situation. Our names were on the waitlist, drinks were in our hands, and we were picking food off the menu before the door even shut behind us. It wasn't even much longer before we were seated with more drinks on our table.
It was only then that I noticed how hip this small diner was: not hipster--more trendy than that.
They pack us in the diner pretty tightly, but not uncomfortably so. Service was good although we did wait a bit longer than seemed necessary for our food. When we got it, it was quite good. They love bison here, and I do too. My bison chili was lovable, although admittedly did not blow my mind. Nothing was cheap (what is in Calgary these days) but the menu wasn't unreasonable. I'm trying to see on their website how much I paid, but there is no chili listed. Best not to rely on the online menu; better just pop into Blue Star
...although if you do, plan to stay for a while.
