The Wendy's next to the Trinidad supercharger is the worst ever, and the dispensary on the other side is also one of my least favorites. But if you go just a block south of the Holiday Inn express on the feeder road there is a Mexican restaurant that is great, and has the best carne asada I have ever had. The best hotel in Trinidad (LaQuinta) is right across I-25. Of course none of this is actually in Trinidad.
Its funny, I live in Austin, but according to TeslaFi I have supercharged in Trinidad more than any other place.
