My wife and I have frequented here several times during our visits here in Wisconsin for both lunch and dinner, by ourselves, as well as with friends.
They have several large dining rooms as well as an outdoor seating area available. The waitstaff has consistently been very attentive, making sure we have enough to drink or if we need more chips and salsa. Their chips and salsa are very good (although their salsa could use a bit more spice) and the come with pickled carrots as well. My favorite dish is the steak with salsa verde, my wife's the carne asada plate. They also have a very refreshing horchata drink available. For lunch we have both had the steak torta as well as the steak tacos; both of which were very good. In my opinion the prices could be a bit better on some of their dishes but the quality has been consistently good time and time again.
Some nights they also have a guitarist floating table to table singing some songs on request. Perfect for a date night, anniversary, birthday or other special occasion.
