We've been there 3 times and each time the food was good (served piping hot, which is important for fries, right?) and the service was fast and friendly.
They have one of those whiz-bang self serve soda machines that let you choose your beverage with the option of adding different flavors.
.... and the price, more than fair.
I gave them five stars because they exceeded my expectations for a burger stand (it's not the Phoenician, so don't expect it to be)
