Truly, truly excellent and authentic Indonesian food. Spicy really means spicy Indonesian-style, so beware! Not a great wine selection, but good local beers on offer. Very good service too. Reservations are absolutely mandatory.
There is one downside, the restaurant is tiny and narrow with a few too many tables. In order to create the optical illusion of space, the restaurant has mirrors everywhere. To avoid this, book one of the two tables next to the window.
