re: Opening a daiquiri shop: what would it take?

I worked at the one in Monroe while I was in college. You dont do shite during the week, but pretty good on weekends. We did between 200-300 during weekdays, but usually between 1200-1800 on friday and saturdays. Lot of cash involved so taxes are negated somewhat if you're smart.

The icee type machines arent cheap, but for the popular drinks like strawberry, rita, and others, they're worth it.

I bet you're looking at 20-30k for start up, not counting rent and payroll.
