Restaurants for teens and 20's

I've a friend with a 16 year old daughter who I am meeting for lunch in NYC...and am a bit perplexed where to take her to show what a cool person I am! 30 years in NYC, but I really don't eat out that much--and when I do it is usually someplace like Sido, sitting on a plastic seat outside! I want someplace sort of trendy-- but not standoffish or too sophisticated. Here are some ideas I heard about after some research online at Chowhound and a few other spots: Cafeteria : 119 7th Avenue New York (at 17th St), NY 10010 212.414.1717 Schiller's Liquor Bar 131 Rivington St., New York, NY 10002 at Norfolk St 5 Napkin Burger Many locations including: 2315 Broadway @ 84th Street; 150 E. 14th Street, (212) 228-5500; Hells Kitchen-630 9th Ave @ 45th Street Delicatessen 54 PRINCE STREET, 212 226 0211 Gemma (Bowery Hotel): 335 Bowery bet 3rd and 2nd Pulino's Bar & Pizzaria-- Bowery and Houston Lunch Menu LePain Quotidien: (all over --these are Soho locations) Grand & Mercer; Bleeker bet Bway and Lafayette; (between Grand St & Howard St) Lombardi's-Spring&Mott 7A Cafe: 7th Street At Avenue A Cafe Orlin (st Mark's bet 1st and 2nd Grey Dog Coffee : 244 Mulberry Street and 90 University Place and 242 West 16 Street
