Looking for Restaurant Where We Can Talk

I will be in the city early next week and am meeting an old friend for dinner. We have not seen eachother in months and while food is certainly important, we are mainly hoping we can find some place where we will be able to sit and talk for awhile and not feel overly hurried or rushed. We aren't looking for anything flashy; lol.

Specifically, I am looking for places on the west side, within somewhat close proximity to Penn Station. Friend is somewhat selective and eats mostly vegetarian, so Indian, Thai etc. would be great. Sit down Mexican (doesn't need to be overly authentic) would also be welcome, as well.
