This place has the best chimichangas in Madison - at least which I have come across. Absolutely fantastic. A flour shell wrapped around the meat of your choice, wrapped in layers of cheese and lettuce, and deep fried. They then drown that puppy in a cheese sauce and top it with lettuce, then serve it with a side of refried beans and spanish style rice. Green and red chili sauces are also provided for your gustatory pleasure.
And then that first bite... heaven.
Taco tuesday, discount beer wednesday, and dollar off margaritas friday are all worth checking out. Also worth noting that every table gets house made tortilla chips and delicious house salsa!
Only knock here is that the service can be slow - it's really a crapshoot. Sometimes you will get your food very quickly; other times you will wait half an hour or longer. Quality of the food also varies somewhat with who is in the kitchen and the phase of the moon.
Don't let that deter you though. Even on an off day, A La Brasa is still quality mexican food. And seriously, those Chimichangas. Oh man, those Chimichangas.
You should seriously check this place out.
