- CPChuck ParkerJun 20, 20263.0This place used to be a great experience. Tonight it felt like our waiter had 3x the tables he could manage. Dishes missed. 25 mins between visits. Now what I would expect from the Four Seasons. Disappointing
- JHjoanell hopfMay 21, 20265.0What a wonderful experience. Our server Ricardo made us feel so welcomed and comfortable. He guided us through the menu which encouraged us to order things we usually would not have. The rest of the staff for so personable, especially Anna. The manager Alexia was extra attentive and we even got to meet the executive Chef. We wanted to stay forever and eat the whole menu.
- RKRobert KunzmanSep 28, 20243.0We went and anticipated a really nice dinner. The restaurant was nice and the staff was nice. The service was not that great and the food was not that great. I expect a lot more out of the Four Seasons. After our $220 "dinner", we went and had dinner again.
