Most frozen margarita places around the strip have the same 5 flavros with different names. Not Evening Call! This particular location has great staff! They will let you sample without pressuring you to buy. They will also make you their own special combos!
My Favs were : Sin City Cider and Jack n Cola ~ Yum!
Although a bit pricier than its neighbor the Rockin Taco, they have a ton more unique flavors.
