Disclaimer: One of my friends used to work there. Even then...
For japanese draft beers like Shiga Kogen (the citrus-tinged pleaser tastes like a great mix between stout and ale), this is the place to go. Also, the tables are positioned for that feel of conversation and maintained private space.
Food-wise, the sashimi is average for the price and comparable to most mediocre sushi trains in Singapore, also not properly cut. The batter for the softshell crabs is too thick and bland, and the sauce accompanying did not help. The chicken karaage was tastier, but the sweet chilli sauce was nothing to remember. The vegetable tempura was decent, but not noteworthy. Their sausage platter would be more deliciously suitable with the beers. Have not yet tried the udon or the soba, and am not tempted to do so.
The service is prompt with the seasoned staff, and terrible with the newly-trained staff.
The curry rice is comfortingly great for hangovers. If you're there for the beer, catching up with friends or to cure a hangover eg. with the umeshu chu-hai mixer, it's an apt choice. If it's for anything else, you'd be better off elsewhere. People-watching is definitely elsewhere, for better views.
