Today I paid a much needed visit to Anna's Taqueria, Boston area staple for delicious, fresh Mexican food. I visited the location near Coolage Corner in Brookline, MA.  I have to say, it is a great restaurant for casual dining and hefty portions of burritos, quesadillas, and tacos.  Excellent chicken, steak, and carnitas burritos with freshly made pico de gallo, guacamole and Mexican rice.  Go with the Super Burrito, rolled up with chicken and all the toppings made in seconds all for about 5 bucks.  They have great, inexpensive lunch or dinner for students and anyone who loves good Mexican and large portions.  Cons include slightly rude service occasionally (when busy, moving customers down the "assembly line"), and an "interesting bathroom" not dirty, but with some "creative" graffiti on the walls.
