There is very little here for vegetarians--and what I ended up getting (a fava bean salad) was tough and had little taste, mostly just vinegar with a really weird chemical taste. Yuck. I would stay away from anything with their vinegar.
Their so-called "meatless" sauce is really "low-meat" sauce... it's got meat stock rather than solid meat. I respect that that is traditional, but a few more options for vegetarians could still be on the menu, making them able to accommodate a more diverse party of diners.
I didn't like what I had, nor the underground atmosphere--however, I don't like to rate one star based only on my subjective preferences, and the service was fine. So, two stars.
