I have encountered many visits to La Casa Loco in Rugby Warwickshire and the service and food each time have been 5 star.
The fajitas are to die for and there is more than enough to fill you up, they come on a sizzler plate and come with pots of salsa, sour creme etc etc and you get 5 tortillers to fill to the brim. The fajitas are not too spicy either which for me is a plus point!!
The menu is varied and main courses start from around £12 to around £17 on average, but the amount of food you get its rare you would manage pudding as well.
The service is good and the food cooked quickly, unfortunately the down side is as its a busy restaurant you have a time slot for your food. The atmosphere at La Casa Loco is a party atmosphere, but I have been with a partner as well as with a party and I didn't find the atmosphere to overwhelming, we could still just about manage a conversation.
The decoration is of a mexican theme which you would expect from a mexican restaurant, however the seats are not very comfortable, so maybe the time frame to eat in is suitable or you would have a very numb bum!!
