La Pachanga in Calgary charges a 17% gratuity on all parties greater than six individuals. This is posted on their menu. The food and drink is quite good (Latin fare), although its expensive for what you get - $32 nets you a appetizer "platter" with one tamale, 5 breaded meat chips, house salsa, two meat turnovers, a roasted sausage and fresh made tortilla chips. The service is acceptable, though not necessarily worth the automatic gratuity. On the upside, the live music is good, the local latin regulars schmooze the ladies into dancing (so those men that don't like dancing don't have to...) and the atmosphere is friendly and inviting. 3.75 stars of 5.
