Apps for Ordering Your Lunch

The kimchi rice bowl sounds good.
For a transplant, Bob Liptak sure is privy to the city in which he’s shacking up. Not only will his new SLU sausage shack The Wurst Place stock vegetarian options and gluten-free rolls, Liptak has mentioned he might develop an app for the forthcoming restaurant. The idea is to cater to the nabe’s bustling lunch crowd: the app would allow patrons to place an advance order, ergo avoiding the lines known to clog other nearby spots. (Apropos the Place, have you read the comments on this post? Juicy.)
The just-minted Marination Station and its four-wheel counterpart, Marination Mobile, offer a similar service, Yorder. Same dealie: place and pay ahead of time, then select a time for pickup.
Considering we live in TechTown, USA, these guys can’t be the only ones to make ordering easy. Know of other eateries going techie?
