The restaurant wasn't too busy when we got there, so we were seated immediately.
We perused the menu for a bit, and then made our order. As you can see, on their menu they rate each dish according to the level of spiciness. We only ordered one 'three chili pepper' dish, the fish hotpot. They asked us how hot we like things, and we went with mild, so I guess they also adjust the spice factor relative to that request.
