I went to El Carnicero on a Tuesday. While El C didn't have any Taco Tuesday specials, happy hour runs from open at 4 PM through 7 PM. You must sit at the bar. While I was there from a bit after 5 through 6:30, there were plenty of bar seats to pick from.
Happy hour got me a good $5 classico margarita and $5 wild boar nachos. Overall $6.50 in savings. I'd never had boar before....it tasted like pork. The nachos were a good serving size and were easily split among three people. They had a nice, mild melted cheese over them.
For my main I ordered machaca; this was from the taquitos section of the menu. The tacos are served in make your own style. Truly soft and warm corn corn tortillas are provided for you to add the meat and sauces too. I loved the spicy salsa verde. The meat was beef brisket. It was well seasoned and tender and I would order the dish again. The portion was very generous. While listed on the menu, coffee was not a prominent flavor that I tasted in the dish.
I've been working my way around town for Tacos the past four weeks or so and to date this place is at the top of the list, though more pricey than the other places I have been.
