"And with the young sexy girls will come a few farangs to admire their looks."
And that might be part of a problem rather than a plus for a business such as this. Who wants a bunch of impolite perving ugly old drunk fart farangs in their restaurant leering at their female Thai customers and staff like they were at a beer bar or agogo bar in Pattaya, making a fuss, having fist fights, arguing loudly, and loudly dropping F-bombs all over where the Thai customers/families/couples can hear (and which word they do understand, most of them, as being highly impolite)? Basically scaring away the very customers one wants to attract. I find it doubtful this would help anyone's business that was trying to actually attract real customers with some good food, decently priced drinks and beers, and some amenities meant for the targeted customer base.
Look around gents. There are many more Thais that spend their money daily in many Thai oriented businesses than there are farang oriented places and farangs. If you can gain their custom you'll do, or can do at least, quite well.
JMHO.
