is there a catch to this???

Actually, I already received the same offer from them.

The free dinner/lunch is true - we were able to avail one for free.

Then they'll tour you around their facilities to offer you a membership in Astoria. You can decline or avail of their membership services (that's where the free stay comes in).

It's not really a scam per se.

sir m2 so you did come and avail for the buffet? did they make you pay for anything? say..service tax or what?
