I enjoyed Holder during my recent trip to Montreal because a local colleague of mine recommended it. I found a very beautiful and spacious restaurant with friendly service, and a very upscale trendy atmosphere that is perfect for a romantic dinner or work event. The bar area also is large to accompany large groups.
The menu is traditional French with many variations. My colleague loved the salmon, and I chose the traditional hanger steak and frites. The fries were delicious, and the steak was A-Ok (not the best I've ever had honestly but good). The complimentary fresh French bread and butter was a wonderful way to start the meal. I chose coffee to end my meal, and it also was dark and tasty.
It's hard to compete in a city of so many great French restaurants, but this is certainly one that stands on its own two feet as a nice place to experience the city's cuisine if you're in the area.
