The Red Bar margarita is indeed a potent cocktail!Los Ranchero's (formerly CoCo's) has very tasty and adequately strong margaritas. Most deadly margarita, though, at least for me is Red Bar. Maybe it's because I've usually been sipping/gulping something else before I get there, but twice I've had two Red Bar margaritas to finish off a beach afternoon and twice I've had to arrange a ride home and some hot tea.
