My sister and BIL went to Birches for VD and said it was absolutely the most horrendous meal and the worst experience they have ever had in a restaurant. They did say that they had good service and the interior was pretty. That's the only good thing they had to say. If you search the Mid-Atlantic board, you will see my review from 2 weeks ago. Cafe Gallery is truly mediocre, but with a great view. Frankly, I think you are sorely out of luck in Burlington. I don't know anything about Blue Claw or the diner mentioned above. I've been to Casamari, but cannot recommend it . I have heard from numerous people that a place called Amy's Omelettes is very good for breakfast. Sorry...
Birches is supposed to be very good, but I've read some not so good things about the place here: http://www.birchesonline.com/.
I've heard good things about Cafe Gallery: http://www.cafegalleryburlington.com/.
Blue Claw Seafood is very well regarded in the area: http://www.crabeatery.com/.
For diners, you have Dolphin Diner: http://www.dolphindiner.com/.
I've been to Casamari - it's pretty good, but I think it's hyped a bit: http://www.mycasamari.com/
Hope this helps.
