We stopped for lunch on Monday to try it out. I was sceptical because Sun Prairie has a couple of Mexican restaurants and most are pretty bad. They have a small menu with the basic items you would find at any Mexican restaurant. Their lunch menu was very inexpensive, most items were $5.99. We tried the enchilada verdes and chile rellenos. Both were amazing.
The enchilada verdes had great flavor and all the ingredients were very fresh. It had a little bit of spice with a great back end tartness. The Chile rellenos were big and very flavorful.
Service was good but they were not busy at the time we went. We got there about 1:00pm.
We enjoyed the meal so much we went back for dinner on Tuesday night. The place was busier and had many families with small children. It made sense because they have a kids menu that was very inexpensive. We ordered the nachos grande, enchiladas verde (again because it was so good) and the enchiladas creamy tomatillos. The nachos were huge and had the perfect balance of chips and toppings. Both enchilada dishes were perfect.
The big selling point for us is they use fresh ingredients. The chicken was firm, juicy and shredded. On the nachos the chicken had great seasoning and crisped up by the grill. Their refried beans are the best we have had. They are not pasty or heavy at all. The rice was fresh and flavorful. I recommend Guimo's to all that love mexican food.
