First @sage ideas are hot, right on the money - especially making the bar attractive to ladies, hence making the social scene alive.
Let me try... though I've no experience whatsoever in the industry

1. I hear low income earners really get/understand small items. Hence I'd not be surprised if you'd sell more if you allowed small/cheaper servings of keg for example.
2. Then there's the normal stuff: the name, some paint, bright posters, clean clean clean, windows, better layout. Bitings/TV are value adds.
3. Bars are one product only atmosphere/service varies. Is it possible to generate loyalty? Regulars treated special and get something on the house whenever they bring a new friend to the pub.
Lastly, [b]what one thing would your customers say your pub is known for?[b] If it doesn't have its special identity, you need to look and listen until you find the one thing people say.... "If you're looking for _______ in Ruai, go to..."
