Really really good restaurant (never used the hotel rooms, so this is only about the restaurant). I've been there 7 times and going back tonight.
AREA is really nice. It's just in front of the falls and the river. The tourist information shop is just 2min walk from the hotel/restaurant. There is a large parking lot at the back so, no issue with that.
FOOD: Ok, not pretentious food, just food, but good one with good presentation. Portions are regular (I could do with more french fries though), you won't leave hungry.
PRICE: Resonnable. Expect £20-25 per person if you eat a la carte and take a 3 course meal with non alcoholic drinks.
I would definitely recommend this restaurant to anyone, it's worth the trip!
