Restaurants continue their meteoric rise in Colorado, with 2015's first quarter sales of $2.8 billion nearly setting an all-time record according to the Department of Revenue.

That’s up 8 percent compared to the same quarter a year earlier. It’s the biggest first quarter in Colorado history, and it just missed the all-time record for any quarter.

While all counties saw growth, Weld County saw the steepest jump in restaurant traffic -- up more than 12 percent over the year. Denver continues to dominate, by far. One in every $5 spent on restaurants is spent there.

People moving to Colorado are feeding sales growth – but it's not the only explanation.  Sales are outpacing population.
