Tomorrow, have your twitter account open and your fingers at the ready. In celebration of Co’s one year anniversary since becoming providers of contemporary Vietnamese cuisine, this noodle bar will give their Twitter followers a chance to reduce the $4 happy hour (4-7 p.m.) price for their beef pho mandu.

Co will post a photo of this unique bite-sized treat and will reduce tomorrow’s price of the dish one penny for every retweet the photo receives between 9 a.m. and noon. So if the thought of enjoying beefy, stuffed dumplings tomorrow for a reduced or even free cost sounds appealing, add @eatatco on twitter and check their page when the clock strikes nine.
