My verdict, Increase opening for natural lighting to come in. And employ light channels, sun, sky, spot lights and spot light-island

350 passes, E4, lights, sun and sky all on.

500k pixels at about 1/2 hour:
It's looking pretty good, for a very difficult lighting situation. The only change I made to your model was to boost the lights by a factor of 5-- 25 watts is too dim (remember these are incandescent watts-- use lumens if you're unsure.) I did this by changing the # of channels to 2 and boosting channel 1 by 5x.
I'm going to let this run a little longer to see how it resolves the remaining areas (the worst are the tops of the stools and the base of the counter. There aren't really many "fireflies" in this one-- just some noise in some brighter areas which is a characteristic of this engine (as opposed to the path tracer where the noise tends to occur in the dark areas.) Almost all of the noise is due to the daylighting which is difficult in this scene. Not only is the primary opening small, but daylight enters the space via the alcove to the left. As a simulation, I'm very pleased with how this one is going. I do understand that it may not be practical for you (although it might in combination with a little PhotoShop clean-up.)
Make sure you're using the latest build-- it make reflective caustics an option-- this pathway will add a lot of noise to this type of scene.

This is a remake of one of Peter Milner's scenes. I dont have the file. I photo-matched it in sketchup and rendered in nxt render for autocad.I just retouched it and increased the resolution.
