Great atmosphere, amazing tacos. If you've never been there before, they open at 5:30pm for dinner but it would be smart to arrive for 5:10pm if you want to avoid a potentially long(er) wait.
I'd highly recommend the scrapple (not sure how to spell it), beef cheek, or cauliflower tacos. They are well-worth the wait to get in.
Only downsides: the music is quite played quite loud, so it's not an ideal location for any lengthy or in-depth conversation. That, and pitchers are expensive.
