I've not seen it be open for a few years now. Some have reported that it was open on "select" days back in june
There are even rumors that it's closed for good (and that would probably be good news, because that sorry excuse for a restaurant was a shame - if you've ever left an open tomato sauce tin can to dry on the countertop for a few days, you'll get an idea of the stench you could smell just after opening the doors ... gross ...)
Just consider that it'll we closed.
If it's open and you're brave enough, then consider it a bonus, and you won't need a reservation anyway.
