I agree with most people here that Mesa Grill is good. Our group of 6 came here for dinner and left quite happily and satisfied.
Of all our dishes though, I highly recommend the Tiger Shrimp Blue Corn Tamale for appetizer and Grilled Mahi Mahi. The creaminess of the tamale and the sweet/ sour/ slightly spicy pineapple sauce drizzled on the fish will definitely send you to heaven!
One disappointment was our drinks. 2 of us ordered "Gimme a Lemonade" (green tea vodka + lemonade). It was very bitter and we could not taste any sour-ness of lemonade. It tasted like water down vodka. But maybe it's supposed to be this way?
I give Mesa Grill 4 out of 5 because it didn't impress us with as much punch as some other places we tried in the next few days.
