Despite me just naming 7 Lives the overall best taco --- Grand Electric is no slouch whatsoever. The taste rivals 7 for sure. But what you'll find here is a WAAAAAY better atmosphere. Actual tables. Liquor license. Hot and friendly (yet hipster I'm a bit too cool for you) staff.
I highly recommend the spicy octopus on top of trying every one of their tacos.
ENJOY!!
