No liquor and you want kids.... tough in many areas to get schools involved. Liquor pays the bills in most cases. You mentioned the other area room eventually getting liquor and increasing their size, a two step in their manner might be advice. Kids will never pay the bills, and your likely to only see them on weekend nights in most cases, especially if you hire a young high school gal to bring in her demographic. I've heard than only 20% of business's such as this survive, and you won't know till a couple yrs have passed. Make sure your able to get outta your lease, and that local ordinances don't require extra this or that before your open. I had to completely redo my bathrooms to code unexpectedly in one of my situations.
