I like all of the above mentioned places, but agree that for a special occasion, you should try a unique Huntington place and not something that you could have anywhere eise.
If you don?t want a heavy breakfast and you are a coffee shop guy and like pastries for breakfast, Nomada Bakery at Heritage Station and Grindstone on 8th St are very worth looking into. I know Grindstone also has some nice bagel sandwiches with eggs and stuff too, not just like coffee cakes and muffins.
If you want more upscale, I think Le Bistro does breakfast. Also, a lot of the nicer Huntington restaurants that aren?t normally open for breakfast have very good weekend brunch, I.e. Sip Downtown Brasserie and Black Sheep.
