I need a suggestion for ordering dinner for my boss and a group of board members... good food at a decent price and somewhere fantastic!
I honestly don't think there's any place in Chelsea that I, personally, think of as "fantastic." Would you be willing to consider restaurants that are nearby, i.e., on the cusp of that neighborhood?
Also, what are the group's food preferences?
And as far as a decent price is concerned, you need to be more specific because people's opinions of what "decent" means can differ radically. So, please give us a per person budget and tell us if that figure includes alcoholic beverages, tax & tip.
In West Chelsea, I really like Cookshop. Maybe you could also try Trestle on Tenth. I haven't been there, but I've heard good things. I think Tia Pol could also work--they take reservations for groups of 6-8 people.
If you don't want to go too far west, Momoya could also work. It's very good, reasonably priced sushi, and the black miso cod is phenomenal. Maybe Boqueria would be good, though I don't know if they take reservations?
