We have gone to La Corte twice now; the first time with our children and the second time in one of our micro dates. We enjoyed both visits. However, we enjoyed it even more without the kids.
The food is spectacular! A little pricey but they do offer an all-you-can-drink for 1,000 yen at certain hours.
We definitely recommend this place for special dates as they have 5-course meals, wine, and champagnes.
