Super friendly staff here. But no drive through. They sell the hot sandwiches, which I always appreciate. They also have a customer of the month... which is a little embarrassing. This month it's a dog. I'm sure the dog is cool with being customer of the month. But personally, if my name popped up on that sign, I'd be mortified. Don't tell the world about my sugar/caffeine addiction!
Summerlin folk seem to like to hang out here with their kids, so be prepared for that. Also, it can get a little crowded - this is a popular spot, especially on the weekends.
