I've eaten here a handful of times, always getting an arepa. They've always been good. The corn cakes are delicious themselves. If going with a group, and some are may be hesitant to try them, you can get an order of just the corn cakes with cheese on them. Sharing that as an appetizer would convert anyone, I believe. She also occasionally has special fillings - one time the special included a fried egg; I was so mad that I read the special board after ordering. Also, the last time I was there (about a month ago), Lis was advertising a Saturday brunch.
