I don't understand all of the glowing reviews for Provenance. My experience was mediocre at best! My family and I went for brunch and the service was pretty terrible. Definitely not the level of attention one would expect from a place that charges $20 a plate for breakfast food! Our waitress was frequently MIA, and when my crab quiche first arrived it was cold. I asked the waitress if she could heat it up, and she took so long in the kitchen that the rest of my party had mostly finished their meals before my food showed up again. Also, those with allergies be warned: my mother ordered the poached chicken waldorf salad, and was rather peeved to discover that it contained onions, which was definitely not listed in the menu description.
I was also very disappointed in the "chef's table" as most of the options were pretty picked over (hardly any fruit) and not replenished the entire time we were in the restaurant. Decor is very boring: modern, but more reminiscent of an office park than a high-end eatery. Given the fact that Provenance is located inside an art museum of all places, I expected it to be much more visually stimulating.
The food itself was tasty, and the reason for three stars instead of two. But I don't think I would ever eat here again.
