So I've been to Brussels many times and I've heard of the "coffin" bar but had just never made my way to it. But since Halloween was approaching I figured now was the time.
Yes the name of the place is Le Cercueil, and it is located right off the Grand Platz.
This isn't just a Halloween sort of decorating thing but a year round event.
The table is a glass covered coffin.
I had heard it was expensive which was true. I heard it was cheesy which was also true. I heard you could get a great beer in a skull mug. Also so true.
My thoughts are you should check it out but don't plan a trip to Brussels just to see it.
