La Casa De Los Abuelos is a popular family restaurant chain with several locations throughout Cancun. The night we went it was jam packed and we were the only tourists checking it out, just lots of local families. They even have a separate area for the Ninos - making it a great family stop.
The menu is casual Mexican comfort food, as well as a range of fresh baked goods.
It's the sort of place you could easily miss as you pass by a local strip mall , but if you are looking for a typical local experience, it makes a great stop.
