I visited Union during the holidays w my husband and sister & brother-in-law for lunch. I ordered the gnocchi w pork & beef ragu. My husband ordered the burger; my sister the polenta & bro-in-law the salmon. We all really enjoyed our food & wine. The portions are big, so a very filling lunch. There are lighter (salad/soup) options too.
The main reason I gave Union 3-stars and not 4 is that they need to work on their interior temperature control. There was no barrier between the front door and the seating area except a flimsy curtain that was constantly being opened. So with the -20C outside it made for a uncomfortably frigid meal experience. Folks at the front bar were fully bundled up in coats while drinking. If they are trying to go for the Ice Hotel experience they hit the nail on the head. My advice spend the money and get a real double door installed.
