The trofie pasta on Boulette's Larder's lunch menu for today looks great, though a casual meal there could eat up your fine dining budget! http://www.bouletteslarder.com/menus/...
If you want, you may get it to-go, and go down the hall and stock up on Acme breads.
Perbacco, which was recommended in your other thread, also does great pastas, but I find they are on the light-side as far as pastas go.
