How do diners rate it?
| Site | Rating | Reviews |
|---|---|---|
| Restaurantji | 3.4 | 234 (food 3.8, atmosphere 3.6, service 3.7) |
| Yelp | 2.8 to 2.9 | 44 to 45 |
| Tripadvisor | 5.0 | 3 (an old page, ranked 75th of 279) |
The Tripadvisor score rests on three reviews and should be set aside.
Which hours should you trust?
Yelp and Tripadvisor agree on 2 AM, with 3 AM on Fridays and Saturdays, so plan around those and call before a very late run. Restaurantji's 1 AM close is the outlier.
