BOULDER - A Trader Joe's grocery store is slated to open at the Twenty Ninth Street retail district in Boulder at 8 a.m. on Valentine's Day, Feb. 14.

The 14,000-square-foot Trader Joe's store is slated to open at 1906 28th St., the site of a former Applebee's restaurant. The restaurant has been demolished and construction work is going on at the site.

Trader Joe's officials also plan to open two other grocery stores in Colorado on the same day, at Eighth Avenue and Colorado Boulevard in Denver, and at the Cherry Hills Marketplace at 5901 S. University Blvd. in Greenwood Village.

Trader Joe's has plans to open five stores in Colorado in 2014, including a 12,000-square-foot store in Fort Collins at the northeast corner of College Avenue and Horsetooth Road.

The new Trader Joe's store in Boulder will join an already crowded grocery market that includes three Whole Foods Market stores, three King Soopers stores, three Safeway stores, Sprouts Farmers Market, Natural Grocers By Vitamin Cottage, Lucky's Market and Alfalfa's Market.

Monrovia, California-based Trader Joe's started in 1958 in the Los Angeles area. The privately held chain has 390 stores in 35 states.
