Good Brazilian restaurant for the in-law?
I will be in Manhattan the first week in June with my fiance and soon-to-be mother-in-law who is from Brazil. We'll be at the Marriott on W. 54th St. Any suggestions for a place nearby that offers a good, authentic Brazilian meal? Desperate to make a good 4th impression, as 1 through 3 failed miserably. (But then, that's another story....)
