The best thing at Los Amigos is their chicken nachos, and the chile rellenos. Best nachos I've ever had. That's pretty much all I eat there. Everything else is, as others have said, very bland. Not bad food, just not a whole lot of flavor. The service is sometimes ridiculously slow, at any hour of the day.
Los Amigos is my favorite place to go whenever I go out on a date or out with friends. The building is near a year old and is absolutely beautiful inside and out. The service is quick and very friendly. You sit down and immediately enjoy tortilla chips with salsa (you can get cheese dip by request for extra cost). The menu is large and has alot of options. Sometimes its hard to choose. Depending on the amount of customers, wait time for your food can vary from speedy to a little wait. The food is served directly off the grill, and you can see the steam rising and hear the food sizzling as it is placed in front of you. The price is a LITTLE on the expensive side, but is overall an amazing place to enjoy an authentic mexican meal in Seneca. I would recommend this place to anybody.
I loved the texas margaritas and the wonderful price of them. The tamales were excellent and the service was good. If you love mexican food and fine dining but are watching your pocket book, this is definetely the place for you.
