The Union Grille is excited to welcome Chef Benjamin Thorpe back to our team.  He was with us 7 years ago and has recently returned with his wife Brenda and their four children.  While he was away his professional journey has taken him to Washington DC, Oregon, Florida and Santa Fe.

Raised in a well traveled family he was exposed early on to the flavors of many international cuisines, as his mother and father sought to recreate the dishes they had enjoyed while living and traveling in southeast Asia and beyond.

These experiences have greatly shaped his culinary focus which seeks to incorporate techniques and flavors from  international cuisine while maintaining close connection to local and regional suppliers to provide peak seasonal ingredients. As a chef he has worked across the industry from coast to coast.

Chef Benjamin has returned with an expanded culinary awareness and fresh approach to Montana Regional Cuisine.

The Union Grille and Chef Benjamin share the same philosophy on food which is to harvest ingredients at the peak of availability for the best flavors and best nutritional offering.  We believe that season and ingredients dictate what we do with them.
