I really like this Starbucks in particular as compared to those around it. First of all, the staff is always very welcoming and extremely friendly. They gladly speak English and French to everyone. They'll recommend drinks or food they enjoy.
As for the atmosphere, it's got that nice sweet spot between deathly quiet for studying and an upbeat meeting spot. I usually go for studying, they have a large table with outlets underneath it and many booth tables for comfort.
