I dropped in at Art Square Cafe for an event in the basement, and not at the actual restaurant on the main level so I can't comment on the food.
For this music and dance event, the basement spot was great!
They had a sweet little bar set up, and the stage was off the left as you enter the basement, seen through a partition separating an elevated stage from the rest of the space. The musicians had plenty of room to do their thing as well as the dancers. Sound was top notch that night too.
Even though it got hot and sweaty in there, it was a perfectly enjoyable experience.
The walls are adorned with some interesting art pieces as well.
Outside the door, there is a nice semi-private patio space at the same level so it was easy to get away from the action without having to hang in the street. AGO is right across the street and was buzzing with one of their evening events, which helped add to the vibrant atmosphere of the evening.
