If I were you, I would come here solely for their Truffle Wagyu Dons ($12.90/S). Topped with sweet sauce, crispy bits of garlic and an ever-so-important onsen egg, it has one of the more remarkable beef-to-rice ratios I've encountered. The lingering aroma of black truffle oil that hits once the bowl is served is also a plus point.
Don't try to order a large bowl unless you have the appetite (and stomach) for it, as portion sizes are enough to leave one feeling satisfied, and still with room to pop by one of the many eateries in the area for a late night dessert stop.
One bit of advice: skip the underwhelming Spicy Salmon Don ($12.90).
