Burrito Bueno is in my opinion, the best Mexican restaurant on the nortwest side of Milwaukee. They save me a trip to the intersection of 5th and National, which has to be the Nexus of Mexican food in Milwaukee.
For me, the ultimate Mexican entree has to be the fajita. It is a feast for the eyes, nose, mouth, and ears. You hear the fajitas at BB coming right before you smell them. And the smell.... it starts your mouth watering immediately. The sauce they add to the fajitas gives them a wonderful flavor. The vegetables (includig carrots) are always fresh, and the steak is tender and flavorful. You truly must try them for yourself.
The entree I order most frequntly is the Burrito Bueno, however. It is huge, tasty, comes with rice and beans, and is an excellent value. You will leave full.
The hot sauce they serve with the tortilla chips has just enough kick to make you want another margarita. How great is that!
The decor is interesting. I have grown to love the pink tables and chairs, although they don't really fit the rest of the decor.
I would recommend that you give Burrito Bueno a try before heading to the south side. You will be pleasantly surprised with the food!
