I love El Chapala's and eat there every other week or so for lunch. They have an inexpensive lunch menu, free chips and salsa (woo!), and quick service that gets me out of there in roughly half an hour. The food is excellent, and the restaurant is very accommodating to single diners (like me ~ I take a book and read while I eat on my lunch breaks). Something off their lunch menu and a soda runs about $7.
