I decided to go one day for the breakfast. I needed a change from my homestay breakfast. Ah real coffee yeah! Omelletes, crepes, yogurt, a juice or 2, muffins, the standby gallo pinto etc. Staff were a bit slow at cooking the pancakes and omellete. However I did enjoy the quality of the food. Note pricing in USD but bet you will be asked if you can give them some cordobas as I did not see a lot of US bills in the till.
I also went later one day for the a cold chocolate drink and a brownie. Not much of a museum not sure why it even rates that part of the name
