You will probably need to queue to be seated as this is a popular attraction. As there is a high turnover of guests your table may be a little grubby.
The waiting staff are variable from excellent to indifferent.
The buns are huge; a meal in themselves, and delicious. Cinnamon is very popular and had sold out when we arrived at 3:30.
The lady in the museum in the basement was very knowledgable and the little shop down there sells the cinnamon butter that we couldn't get upstairs on a bun.
The museum is tiny but fascinating nonetheless.
