Fun Irish-pub type vibe with a great beer selection and not your typical bar food. I love the oysters on the half-shell, salads, sandwiches and fried zucchini/mushroom combo.
Casey's offers inside dining and a bar - but the expansive patio is the hang-out spot. The clientele is varied and full of regulars. People from all ages and backgrounds hang out here but it's especially popular with ASU students, staff and faculty.
The only downside is parking can be difficult, service sometimes slow and it can become fairly crowded - especially on the weekend.
