Go for good mexican food. The combo meals are very good. Enchiladas, ChimiChangas, tacos are good. The beverage options are limited.
Bon Appetit 
Their are not too many options avilable for mexican cuisine lovers in Delhi. Salsa Salsa is probably the only stand alone mexican resturant. It is not authentic mexican but i doubt we'r gna get a better mexican food then at SS. Nachos are great, though i just wish they were a little more liberal with the quantity. Quesadillas and burritos are enough for a hearty meal..
Oh and ginger ale lovers, try it with the fajita...
Peace!
Salsa salsaa has one of the best mexican food in india and it is worth the effort driving from delhi to gurgaon to dine here. There food has a unique touch to it and is reasonably priced which was quiet suprising. It was recommended to me by my friend in the US. and we have become regular there. salsa sizzlers & ice creams are also quiet amazing. GO & TRY.
Very good value for money. Tried the place on a lark some years backa nd came away plesantly surprised. I consider it a much, much better option to Rodeo; in fact it is possibly the best joint for the kind of food they serve. Very mundane decor, but simply great food.
