The Modmarket in Longmont is celebrating its birthday. (We’re not sure which one, but we think it’s been one year since they opened.) From today, Friday, October 30 to Sunday, November 1, buy one entrée and get a second (of equal or lesser value) for FREE — just say “BDAY” at the register to redeem. And, if that’s not enough to make you join the party, Friday evening they’ll be giving away a piece of birthday cake with each entrée from 5 p.m. until it’s all gone. The offer is only valid at the Longmont location — 700 Ken Pratt Blvd., 720-494-1655. The offer is not valid for online, phone or catering orders.
