Every Tuesday, the SoMa sports bar rolls out "Disco Taco Tuesday" — a weekly deal featuring $1 margaritas and, presumably, enough disco-infused energy to make you forget that your rent is due in six days. It's the kind of straightforward, no-nonsense promotion that makes you wonder why more SF bars don't just... try to get people in the door with prices that don't require a second mortgage.

Look, we're not here to tell you how to spend your evenings. But we are here to point out that in a city hemorrhaging small businesses — thanks in no small part to sky-high operating costs, byzantine permitting, and a regulatory environment that treats every entrepreneur like a suspect — it's worth celebrating the ones that are still swinging. Underdogs isn't asking for a tax break or a city subsidy. They're just slinging cheap margs and tacos on a Tuesday night and hoping you show up.

That's the free market doing what it does best: giving people what they actually want at a price they're willing to pay. No task force required. No Board of Supervisors vote. No six-month environmental review of the disco ball.

SoMa could use more of this energy. The neighborhood has struggled with foot traffic and vacancy issues for years, and the businesses still operating there deserve your attention — and your Tuesday nights.

So if you're in the area and looking for a reason to leave the apartment, Underdogs is making a compelling case. Dollar margaritas won't solve San Francisco's problems, but they sure make them easier to talk about.
