TL;DR: 3-3.5/5 Make a reservation if you're visiting on a weeknight to avoid the long wait (they don't accept reservations on the weekend). There are some hits and misses on the menu. Know what to order. I recommend the creamy cheese udon and mabu roasted milk tea.
Be prepared to wait for at least 20 minutes to be seated if you're visiting past 6pm. Food quality is decent, there are some hits and misses. I've been here multiple times so I try to stick with my favourites, the creamy cheese udon and the mabu roasted milk tea. The cheese and cream sauce on spaghetti and the creamy cheese udon are actually the same despite what it says on the menu, though both are good. The roasted meat ball bolognese spaghetti is nothing special, something you could make at home really. The sizzling hot plate we ordered did not sizzle.. which was a bit disappointing. Service is generally good. There are a few servers who are more attentive, they brought us extra napkins without us asking. A major issue I had was when they began wiping down the table beside us and the strong chlorine smell hit, really ruined the experience.
