Slate Bistro and Bar is located inside of Trilogy Golf Club at Power Ranch. It is, despite the guard gate, open to the public. They serve breakfast, lunch and dinner. I have eaten all three meals there and they do them all well. In fact, Slate has been nominated for the Best Breakfast in Gilbert 2014. The prices are some of the best I have seen for both food and drinks. There is a full bar as well.
Slate has a very nice ambiance and feels as though you are in a nice restaurant without the stuffy air. It is a great place to grab a meal after a round, get a few drinks for affordable prices or have a long meal. The menu has a little bit of everything to hit all tastes and they do offer specials on certain nights. There is even live music on certain nights, usually Mondays, Tuesdays and Thursdays. Make sure to call ahead on weekends as they do sometimes close for weddings. They also do offer reservations and while in snowbird season helps.
Slate is a really good, consistent non-chain restaurant in an area lacking restaurants. Definitely a good find.
