Based on Trip Advisor reviews and the menu, we decided to try Grapes for dinner while staying in Banff about 10 minutes walk from the hotel. Our experience was so positive that we went back for dinner the next night. Overall we enjoyed both meals, but the quality of the food was a little inconsistent. However, the service was excellent at both meals, and the cozy and romantic ambience (to me it seemed like an old English lodge or small dining room in a castle) was just right for a special vacation meal.
At dinner the first night, my husband had venison medallions with "port macerated" berries and walnut (see menu for full description: http://www.fairmont.com/banff-springs/pdf/bsh-grapes-menu-june-2013/). The meat was perfectly done and tender, and the sauce/glaze was delicious (I kept stealing from his plate). The server recommended Cedar Creek merlot with it, and my husband said the wine was also delicious. I had the salmon bouillabaisse from the "healthy" menu (it is a DASH dish), which included mussels, clams, and navy beans in a saffron broth. I found the flavor a little bland (I tend to like salty dishes but was trying to be healthy at this meal), but the salmon was done right and my husband ate some of the dish and liked the flavor. I had a pomegranate lime non-alcoholic cocktail, which was refreshing and not too sweet. Good, very fresh, crusty bread was served with dinner. Even though we were full, as a chocoholic I had to get the Valhrona dark chocolate mousse for dessert. It was actually three parts--chocolate cake, near-solid chocolate mousse, and cream. We shared it and agreed it was decadently rich.
My husband thought this was a "perfect meal" and the venison medallions were among the top three dishes he's ever had. The meal was expensive (most entrees are $32-$44 and desserts are $10, though you can make a meal of less expensive appetizers and sharing dishes), but we felt it was worth it for a special meal on vacation.
We went back for dinner the next night and had the same excellent service experience (both waitresses seemed to remember us, and we enjoyed chatting with them). This time I ordered the venison medallions, but one of the medallions was overdone so that was disappointing. My husband had the Alberta beef tenderloin, which was perfectly done with very good taste. He had Syrrah wine and I had a kiwi gin cocktail--both were enjoyed. The bread did not seem quite as good in texture or taste as the night before.We skipped dessert this time.
For the money I feel that they should be more consistent about food preparation, but overall both meals were good experiences.
