I've been to Ground Control for coffee, beer, and food, but would only return for the beer, of which they have a great selection and reasonable prices.
They have a beautiful La Marzocca espresso machine, but their in-house roasted beans taste inferior to many mass-produced brands.
The one time I ordered food it was pathetic: Pizze margherita that were over-sauced and under-cooked, buffalo mozzarella tasted off, no cornichone, no char, and no spotting. The Phoenix area probably has more awesome neopolitan style pizzerias per-capita that any city in the U.S., but ground control's pizza is barely edible. The poutine and wings were even worse--like what would happen if some some highschool stoner friend was given access to commercial cooking equipment.
