The University of Maine Dining Services has added an online to-go ordering feature for three of its most popular Union Marketplace stations, reports The Maine Campus student paper. The service, through vendor Tapingo, allows students to use their smartphone, tablet or computer to order meals from the Union's pizza, deli or grill stations between 11 a.m. and 5 p.m. Monday through Friday and pay either with their student account or with a credit card. The dining department hopes that the added convenience will help increase lunchtime sales at the Union, where long lines during peak periods can discourage potential customers with limited time for getting a meal
