Translation of quimera

There were no lights on the highway and hardly any cars, but quiet a few motorcycles and funnily pedestrians walking on the emergency lane. There was a tropical atmosphere in the air, I liked it.
The other visitors in my group were from the United States, Canada, Germany and from other parts in Mexico. I need to say that it was so much fun to meet people and spend an entire trip with them.
We felt a little awkward to be the only people in the restaurant and felt a little uncomfortable having taken with us another couple. In addition the Uruguayan cook and owner was drunk, but the food was excellent.
