Break even, IMHO, isn't okay. If you're just slightly above break even, then it'll take a heck of a long time to recoup the 300k you've put down on the franchise.

Kung sa SM, sure-hit naman talaga ang Zagu, or almost any other "pang-masa" food stall that has good name recognition. The worry is: ganyan ba kalakas ang foot-traffic sa mall na pagtatayuan mo?

Pero, if it were me... maybe I'd go for it. It's easy to waste that money on other things, and if you don't have any urgent home repairs to do and you have excess money in the bank after paying off the fee, what the heck, right?
