I went in for the weekday lunch buffet. My experience there in short:
The place was a bit crowded but there are also plenty of tables so you are likely to be seated fast even without a reservation.
The ambience is victorian and comfortable.
The selection of appetizers, salads, and desserts were superb. There were a satisfying number of items in terms of quality and quantity. The food ingredients were fresh.
There were not many items in the main dishes section. The quality was good but you might want for more.
In total the fee was around 40. paid the tips gladly because the experience was great. I would recommend this historic place to anyone.
