Durango in December

I will be taking my daughter for a quick overnight trip to Durango for her 21st birthday on December 21st. We will be only staying one night, arriving in town the 21st spending the day in town then skiing at Purgatory the 22nd and back to Albuquerque the after skiing. She just wants a fun, inexpensive place to eat the night of her birthday. She's a very healthy eater so a place with chicken would be great. Casual dining but she wants to "order my first drink ever" so they need to serve alcohol. Does anyone have a suggestion for a fun inexpensive restaurant in Durango?
