Not sure if this is the same location because my receipt shows this cafe name with only one N in Siena.
Regardless, this is located inside the Suncoast Casino. Beautiful west side of town, with views of the strip. Great place to go to during the middle of the week, which we did. Less crowded and better service.
I went with the Tuna Melt, which was very good as far as tuna melts go. My wife went with something called Crispy Tofu. These are deep fried sticks of tofu. Though I would have preferred a thinner batter, they weren't bad. If they had a way of grilling the tofu, I would have ordered it myself. Well, my wife didn't finish them, but they did make good leftovers.
Overall, good service and food. But do yourself a favor; if smoking bothers you, which it does us, ask to sit in the back of the restaurant, as it is close to the casino.
