Okay, so I have a friend coming in from Ohio. She's extremely finicky about what she eats. Zagats will not help me here--need human advice. We have two dinners that we need to figure out. Next Friday and next Saturday. One night could be Mexican and the other Chinese, she's also willing to do Italian or even American. It needs to be below 72nd street, and it needs to be in Manhattan, and it needs to be below 20 bucks for the average entree. Also, the Chinese place has to have sweet and sour chicken. One night has to be Chinese the other night could be Italian, Mexican, or American. Fun places. Not too small. Not too far downtown. Chowhound geniuses will be thanked profusely!!
