Try hosting a dinner party at your house where you plan and cook the meal. That way, you still get the social interaction you are looking for, without going to a bar. Have theme nights where you try different things, like "Thai night", or "Italian night". Just make sure no one brings wine
Follow up dinner with some board games like Risk, or Monopoly, or Pictionary where you have to focus on the strategy of the game rather than focusing on the fact that you aren't drinking.
