well there are many house wine places around Bangkok. The one that I've been to is in the middle of Thong lor soi 10. It is like wine tasting place with chilling atmosphere. Not sure about the lunch thou as there snacks there are like cheese, small sandwiches.

Was in Bangkok for few days. As far as Koi in LA is pretty good, decided to check it out in Bangkok. It was a bit different, but really nice as well. Good thing is there is no waiting line (but not so mane celebrities as well ;) ) But much more fun though. The food is good, pricing for Bangkok is a bit above average, but if you compare to LA much less. Quality as good as in the states and the service is amazing.
SO i would recommend for those who want to have a nice dinner and just spend an incredible night in Bangkok....
