When Editor of Munch says jump, Munch says, "How high?" When Editor of Munch says write, Munch says, "How long?" When Editor of Munch says "Don't let the truth get in the way of a good story," Munch says, "How right you are."

And when Editor of Munch says that he stumbled upon a delicious Mexican restaurant on the South Side that would make for a fine Munch review, Munch thought that sounded like a fine idea.

The Mill Site Tavern/Los Amigos is at 2512 E. Carson St. on the South Side. Call 412-432-7118. Closed Sundays, Mondays and Tuesdays.

The Mill Site Tavern sports a handsome bar -- one of the oldest in Pittsburgh, and beautifully restored several years ago. With EOM in tow, however, Munch wasn't about to imbibe at lunchtime.

So the party of Munch sat in the dining room, a large space adjacent to the bar complete with an elevated stage and a second floor.

As far as Munch can tell, the dining area is called Los Amigos -- and was formerly known as Taqueria Taco Loco, which moved from Jane Street.

A sign outside read something to the effect of "Most Authentic Mexican Food in Pittsburgh" and Munch can vouch for the fact that there was an actual woman of Hispanic origin doing the cooking -- something of a rarity in Pittsburgh's Mexican restaurants.

The menu is mainly Mexican, ranging from $2.50 quesadillas to $16.95 steak fajitas, with bar standards like burgers and onion rings thrown in for good measure.

Along with Co-worker Whom Munch Owed Big Time, Munch brought Tall and Hungry Co-worker of Munch along for the occasion. And the foursome embarked on a hit-and-miss dining adventure.

Guided by the expert hand of EOM, who seems to have adopted Mill Site Tavern as his home away from home, Munch sampled some delicious things.

The banana pepper quesadilla ($2.50) was crunchy on the outside, creamy and spicy-smoky on the inside, with the surprise ingredient of soft chunks of potato.

The combo enchiladas ordered by EOM featured tender pieces of chicken and beef ($12.95), dressed with an earthy mole sauce. CWMOBT was so satisfied with her chorizo burrito that the egregious error for which Munch owes her big time hasn't been spoken of since.

To paraphrase Mother Goose, when it was good, it was very very good. And when it was bad it was horrid.

TAHCOM -- bursting with enthusiasm over participating in his first Munch -- ordered a daily special of chicken chimichangas, expecting a crispy shell mixing with molten cheese. Instead, he got a crust resembling something in between a saltine and "Mexican matzoh" filled with a bland yet oily chicken mixture.

"It wasn't just the worst free chimichanga I've ever had -- it was the worst chimichanga I've ever had," he pouted, consoling himself with bites of EOM's enchiladas.

Munch had similar feelings about the chicken filling used for the chicken taco ($2.30) and even more unpleasant thoughts toward the fish taco ($3.30), which was neither crispy nor tangy nor good.

Never one to let the truth get in the way of a good story, EOM was still pleased as punch with the place. Munch would go back -- if only for that cheap and tasty banana pepper quesadilla -- but Munch wouldn't get too adventurous.
