Yes, I've tried the veggie options. I remember a slimy veggie lasagne and some very nasty edamame beans with hoisin sauce. (We discussed those once before.) I am not a vegetarian but I do enjoy a lot of vegetarian food so it is often my first choice. I'm not a picky eater - in fact the exact opposite - I eat almost everything, and so does Mr H.
We're not looking for fine dining - just something that we will enjoy, but there have been many times at BOS when it was so bad it just wasn't edible. Either you have been very lucky or we have been very unlucky, but we have found the food consistently bad.
