The service is very attentive, given the price of the drinks at the bar.
I had the house ceasar 2.0 and costs $14. This specialty drink is a fancier version of the casears at your average pub (ie. special miso base.) The server came by twice in the span of 30 minutes to see if we needed refills on our drinks.
Since we did not get to the bar until 10:30 pm on a Tuesday, it was quite busy with a very corporate feel. I think there was a party of some sort being held. The atmosphere was lit lightly but you could still carry on a conversation with your group (ie. the music was not too loud).
The convenience of this restaurant must be factored in as it is at Brookfield Place which is steps away from Union station.
