Venti is across the street from my office so we go there with clients regularly for business lunches.
Venti's isn't bad, the food is usually very good, the service is adequate but as soon as more then 4 tables have people at them the noise level just gets uncomfortable if your trying to have a conversation
They have a new lunch menu everyday that includes 2 pizzas and 4-5 other main dishes and 3-4 appetizers. I've never had something that was bad, I've had dishes I didn't think great but that was more a question of taste then a question of quality.
The service is a little slow for a lunch time crowd and if I was going to eat there without clients I would probably be pushing them to bring out my order much faster then they do. They run lunch like they would an evening meal where you have more time to spend eating with friends.
The bigest issue with this place is the noise! The acoustics in this place are horrible, as soon as there are then 10 people in the restaurant and you won't be able to hear the person sitting across the table from you. But for a quiet tuesday lunch it's a nice place to go and the price for the table d'hôte isn't outrageous as they can be in old montreal.
