I feel a need to contribute more to this board instead of just reading all the time--so here goes.
Two French places I have been recently have really impressed me with the quality of their food and their reasonable prices.
One is Asterix (5561-0980), near TBS in Akasaka on Akasaka-dori (and near my office). I have been there MANY times for lunch, and a few for dinner, and am never disappointed. Lunches are a bit on the extravagant side, with a 1500 yen course and 2000 yen course, but they include an appetizer, main course (fish or meat), and dessert plus coffee or tea. For the volume and quality, I think it`s a bargain. At dinner, courses start from 2500 yen, up to 7000 yen. They have a very extensive wine list (all French, so I can`t really comment on its quality, knowing nothing about French wine, but again have not been disappointed). At dinner you can also sit at the counter and order a bunch of appetizers and some wine. Their cheese is fabulous. The place is small (and in a basement)--probably seats 25-30, with 10 seats or so at the counter, so if you want a table, I`d reserve (reservations also possible for lunch). The disadvantage to the counter, particularly at lunch, is that it`s an open kitchen and the chef does not seem@to be a morning person--he quite often yells at the staff. But he`s a damn good cook. Menus in French and Japanese.
The second place is called Weinberg 2, in Kanda Ogawamachi (near Ochanomizu--sorry, can`t find a number right now). This place is actually owned by a local sake shop that also imports dry German wines (disclaimer--this sake shop is where I take classes, and I`m a big fan of the owner). So, it's German wine and French food (an odd combination, but hey...). Again, dinner courses around 3500 yen--appetizer, main, dessert, coffee--with no complaints about quality or volume. They also have excellent cheese. And, since they want you to taste the wine properly, it's all non-smoking! They also have one big table where you can sit and have wine by the glass and appetizers. Again, a small-ish, in the basement place. I think they have a menu in French as well as Japanese.
