We stayed at the Westin (attached to this restaurant) while visiting Montreal.
We stopped in to have a drink and some appetizers. When sitting at the bar they will give you a bowl of nuts. Also, their cheese/meat board is delicious.
They have a decent selection of wines, beer and liquor.
Service was attentive and friendly.
There is a parking garage as part of the hotel, but street parking is easily available if you want to take the time to look.
I would definitely recommend stopping in for a drink or 2.
