A new delivery service focused on providing home delivery from Portland's best restaurants launches here Wednesday.

Caviar, which will waive its $5 delivery fee for first-time users, kicks off its local service with 15 restaurants, including Lardo, Pizza Maria and PaaDee. Email alerts let customers know when new restaurants have been added.

"Caviar is a service that can turn any restaurant, eatery or food truck into one that delivers," explains Caviar CEO Jason Wang.

Founded in 2012, Caviar was purchased by Square, the mobile payment company, last year. Portland is Caviar's 15th market -- and 10th city -- nationwide, following in the heels of the company's recent Brooklyn expansion. It joins a field of online delivery services including GrubHub and Delivered Dish.

"The key difference is we actually do the deliveries," Wang says. "When you visit our service, you'll know you're getting high-quality food, because we curated the best restaurants: The porchetta sandwich at Lardo, the fries at Little Bird, Blue Star Donuts, etc. We really take our time and only work with the best of the best."

Caviar's coverage area for Portland stretches from the West Hills east to 82nd Avenue, south to Southeast Johnson Creek Boulevard and north to North and Northeast Mason Street.
