After my first visit to the Sachs three weeks ago, I've stopped in for every Taco Tuesday since. They definitely lived up to their hype for me, and you just can't go wrong with $1.25 tacos and cheap beer.
They have a large variety of taco fillings, and they're definitely a step above your average bar tacos. The atmosphere is that of a no-frills dive bar, so I didn't expect the food to be as good as it is, but it's phenomenal. I'm looking forward to trying out their Wing Wednesdays, and they also have $1 cheeseburgers on Thursdays. You really can't beat that.
To be fair, the reviews here are semi-accurate about the service -- IF you come when they're slammed. I think a lot of reviewers here are expecting way too much from a busy neighborhood bar. Go in on an off night, or at least not at prime taco time and it's a 180 difference. Moe is great! If you can be chill about an occasional wrong order and slower service, you won't be disappointed. The worst that's happened to me is I've been accidentally served extra tacos. That's not a con in my book.
