We did a fancy prix fixe takeout meal during quarantine that had a wine braised beef roast, with mashed potatoes, roasted beets, and a plain "salad". It also came with two servings of chocolate mousse. The staff were knowledgable and reassuring. Unfortunately, for the cost of the meal (~$100) it was a bit of a let down in terms of flavor/how unique the food was. I didn't have any negative gluten reaction though.
