Best Western and Khmer Restaurant in Siem Reap

We started out life in 2004 in the Old French Quarter in Siem Reap. In 2009, we outgrew our property and moved to a new and current contemporary restaurant on what is now known as Abacus Lane. Our current location was designed by the award-winning French-Khmer duo Ivan Tizianel and Lisa Ros. They created a stunning dining room with modern and elegant features. Most of all, they created our beautiful tropical garden which is a favourite place to dine for most of our guests who want to get the full experience of Abacus Restaurant.


Abacus Restaurant is busy all year round and making a reservation is strongly recommended. We can’t promise you a table if you arrive without a reservation.


With direct bookings on our website or Facebook page, you will be rewarded with 1 FREE refreshing drink (1 drink for 1 pax) to refresh your mind before starting your meal experience with us.

As you can see from our TripAdvisor listing, guests enjoy our fine dining, nice garden, and Fine dining experience, our delicious meat. We have created what we believe to be one of the best  restaurant in Siem Reap and we have 200+ reviews which all say the same thing!

We created a special private dining area in our restaurant for up to fourteen guests to enjoy a meal in private. This popular room is fully air-conditioned and private from the rest of the restaurant. We also have our main dining room which is cool and comfortable and looks out into our beautiful tropical garden. We have worked hard to create a great ambience and nice atmosphere.

Traditional Meets Contemporary

We revise traditional western cuisine with a modern Khmer twist. Our guests are looking for a unique dining experience and we aim to give it to them! At Abacus, the food and environment is important, but we believe that our service is equally as important. We also believe that our location away from the busy and loud centre of Siem Reap helps us to create a peaceful environment suitable for our unique dining experience.

Our menu is accompanied with an international drink list which features local and international wines and beers. We also have a range of spirits, cocktails, fruit juices and soft drinks. The best food is always combined with the best wine and we have a great selection of wines from all around the world. Our food menu has both a la carte and a set menu available.
