I've been to Takano's a few times. Take Bus 18 to the "Akasaka" bus stop. It's 230 yen from the Kourinbou bus stop (in front of Daiwa) in downtown Kanazawa. When you get off of the bus, it's about a 5 minute walk to the restaurant. It looks a lot like a house, so take a good look at that Google Map so you know where you're going ahead of time!
Other than that, their prices are reasonable and they offer a great "Healthy Set" with dessert included for only 1,580 yen! They have other entree options that are in the 800 yen range -- but I recommend the "Healthy Set"!
Cons: hard to find, not downtown, closes early
