Is it open at lunch time for steak sandwiches?
Yes, it is open for lunch. This does not have all the frills of other places but the steak there is possibly the best available in Sanur.
Unless you are a real big eater order one burger and share between 2 of you. I have taken about 50 people there and all have been impressed by the food and the simplicity of the place.
The beer there is also very cold.
