I would like to amend and say that to miss Nutshell or Blossoming Lotus (particularly, Nutshell) just because someone eats meat would be a shame....Nutshell is quite a gem and vegan. I say this and I'm a traditionalist omnivore.
IMHO, it's easier to list the places that AREN'T veg-friendly than the ones that are (off the top of my head, carnivorous ones would be Podnah's and Beast). That said, one place I that I think should be included as great for vegetarians is Higgins.
Farm is pretty good. There's fish on the menu and several vegan choices. Decent wine list, nice bar, nice setting...service can be a bit spotty and sometimes not so good, but not always. I'm a meat lover, but I really like their herb crusted tofu with marsala mushrooms.
