If Barque is busy, you'll likely be suggested to wait here for your table. If you're not particularly starving and want a drink, you should just stick around.
Barque butcher bar is also a full scale butcher shop and likely bigger inside than it's restaurant counterpart. It's a lot less busy, the staff is super chill and they have an extensive liquor shelf that includes hooch (moonshine baby!). Cocktails are on point.
The menu is isolated to more snack and sharing items, but they carry stuff that Barque actually doesn't serve yet like the chorizo ribs. I suggest the cod and crispy rice if you want to mix it up. Did I mention it's open until 2am everyday?
