Of the four of us who went through to Beleza for breakfast, I was the only one to actually have the R12 breakfast. (For report-back purposes I resisted the urge to super-size my morning-meal.) My compatriots had variants that cost between R18 and R25, which is still very cheap for breakfast.
All in all, our breakfast at Beleza was definitely worth the trip. The food was delicious, the service was friendly and the location - just great. (Oh, and they have free wi-fi too, by the way.)
