Super grateful that there's a restaurant attached to the spa! While the staff were really nice and the location can't be beat, I would not recommend going out of your way to eat here. We had both breakfast and lunch at the CR Grill since we spent a full day at the spa, so after sampling four different entrees, I can tell you with certainty: it's fine.
We had an egg sandwich with roasted pepper and an order of chicken tacos for brunch, which were okay but all very bland. Then had a Caesar salad and hummus flatbread for lunch, which were quite underwhelming. Everything was lacking flavor.
Truly forgettable, not worth a special trip, but it will stave off hunger if you're planning to be in the spa for awhile.
