For me the nightlife consists of sitting in the plaza eating ice cream.  There are many, many holidays, with parades, fireworks, dancers and live entertainment in the plaza.  Sometimes a circus or hypnotist will arrive and these can be quite entertaining for $2.   At other time they have amusement park rides. On Saturdays they often have live music at the local restaurants - usually  at Wala Wala or upstairs at McDonalds.

Dining out is another big entertainment - the tourist type restaurants cost about $6 to $10 for dinner - some of the favorites are La Isla, known for its seafood, McDonalds, Wala Wala, Casa del Canibal, the Wakame Gourmet Chinese Restaurant and Cha Cha's (El Cocodrilo).   This month's pick is Casa Del Canibal - they have excellent pastas and American style dishes for 60 to 80 pesos. There are a number of other cheap Mexican places scattered about and some of them are quite good. My favorite is Traditiones on the same street as the police station. By the way, the taco stand in front of Traditiones is about the best in town but doesn't open until 7pm.

There is a jazz club - San Blas Social Club - right across from Cha Chas restaurant (El Cocodrilo), which serves drinks at night and coffee in the morning.  Sometimes they have art shows featuring local artists. It's a good place to meet people.
