Recently we got a Free Bottle of red wine at one of our local ventas after we had paid the bill.  It was for us to take home and have there.  This venta is a place we go to regularly and has a very good reputation locally.  The reviews on tripadvisor attest to this. 

Everything about the place is classy.  The decor is very modern, not your typical rustic style venta.  The service is excellent.  The owner always makes time to come over and chat to you and makes you feel welcome.  The food is the best part.  It's modern Spanish cooking, beautifully presented, with generous portion sizes.  It's not the cheapest place but I think it represents excellent value for money.  In the 5 years we've been here, it's never let us down.

We used to go mainly for special occassions, a couple of times a year, but recently we've been going every month or two.  

We were pleasantly surprised the last time we went when we received a complimentary Bottle of wine for us to take home.  This was after the complimentary drink you get after you've finished (I usually opt for the Pacharán!).

I don't know if everyone got a free bottle of wine or if it was just the regulars that got it.  Either way, I thought this was a really good bit of PR, and of course, we will be returning soon.  So I guess their plan worked!!
