This is an off-the-beaten-track real Mexican restaurant that is popular with locals. Visitors will not normally find places like this.
Arapicio's is just west of Avenue K in Plano on 18th Street.
While the restaurant is very real and very casual, the food is great, and a tremendous value.
They are closed Monday, but open 6 days a week from 6:30am to 7pm.
They have a dining room, but we mostly enjoy going there for Sunday morning takeout. They have breakfast tacos (Taquitos) which contain various combinations of eggs, bacon, potatoes, and beans wrapped in flour tortillas. I usually go and buy many Taquitos and a Sunday newspaper, and bring it home.
My wife loves their beef tripe and hominy soup (called Menudo).
They also have a small bakery, and of course lots of flour tortillas and chips packaged to go.
They also have lunch and dinner, but I have only been there for weekend breakfast. This is a small and hard working place worth finding.
