It follows from this that we find the 3-point restaurant to be over-powered. Take this one first, and you can pull cubes defensively from your opponent and they will never catch up.
I've not seen the problem, but I'm wondering from the above if you're playing correctly. The 3-point bistro has no special ability - and it's available to both players.
Further, you can only play defensively to a limited extent, since your opponent will typically get first draw of some of the colors.
Could you describe in more detail how you're seeing the game proceed?
