I bet it isn't!
I have been to C&C in Bangkok (and there at least two more branches in the provinces), and the decorations made of condoms are worth going once. That was two or three years ago, and I don't remember the food or the prices, which means both were ok by my standards.
If you like wine, rather bring it from Europe where it will be cheaper and more choice. I don't drink wine, but I like cheese and sweets, and I bring it from Germany.
