Pampano Taqueria may only be take away but there is a restaurant attached, with roof garden. I've eaten there only once. It was ok and I might try it again under the right circumstances. You might also consider Seo on 49th between 2d & 3d, Donburiya on 47th between 3d & Lex, Brasserie on 50th bet. Park & Lex, Oyster Bar at Grand Central (oysters only), Sophie's Cuban on Lex bet 41 and 40, Avra Estiatorio at 48th & Lex. Chikubu, Aburiya Kinnosuke, the Palms & Smith & Wollensky--lots of places and more if you do a search you will find more as there are often questions about this area.
Byblos, on 39th, just east of 3rd, is a Lebanese restaurant with very good food. They have lunch specials for around $12. My favorite is the cold combo plate. Eat in or take out.
Wu Liang Ye, on Lex, b/t 39th & 40th Sts., serves very good Szechuan cuisine. Lunch specials are around $6.
AQ Cafe, in the Scandinavia House, on Park Av., b/t 37th & 38th Sts., is a cafeteria-style set-up. It's a satellite of Aquavit, so Chef Marcus Samuelsson is in charge of the cafe's menu of sandwiches, salads, hot dishes, etc. (Love the Swedish meatballs!) Plenty of tables in a large, very pleasant lobby space.
Sarge's Deli is on 3rd, b/t 36th & 37th. Lots to choose from on a menu, and the food's pretty good.
Carl's Cheesesteaks is on 3rd, b/t 34th & 35th Sts. Delicious! It's pretty much a take-out situation because there are only two tables in the back.
Pampano Tacqueria is on 3rd, b/t 49th & 50th Sts. I've never been but have read some good things about it. Take-out only.
Hope this helps to widen your lunch horizons. :-)
