As a first-timer to Paintbox Bistro to see a jazz band on a Friday night I must say that this place is an good venue to spend an evening while watching a show / comedy / concert that they so often host. Mind you, there is a nominal charge if you wish to sit in the lounge (free to mostly $10).
The place is well maintained and clean with smart decor. Anyhow - the service was stellar with our server being extremely attentive and helpful throughout the night. I practically lost count on how many times our server asked us how we're doing. On ambiance, I'll provide it a 7/10 while service 9/10.
In terms of food - with price ranging $15-$20/plate on the main course I would say that this establishment deliver on that value. We ordered the steak and it was cooked correctly to our liking and seasoning was good. The frites that comes with the steak is also cooked crisp and has good amount of seasoning. Although my only complain was that we had only been given 5-6 slices of meat - wish that they would consider the portion size.
Overall - service was superb but food is just OK. I would go back to Paintbox Bistro for an event / concert that they may have in the future but can't see myself going back just for dinner.
