They have a few kinks to work out (like accepting too many people in the door and not having enough tables) but overall OMG.
I'm not a vegetarian, so I wasn't over-the-moon about trying this place out, but it will probably quickly become one of my favorites.
For food I've had (so far): Pierogis (yum!), the baba jaga (fantastic sandwich and heavy); my favorite - kartofle (potato apple lingonberry yogurt), and the vegetarian special sandwich (not my favorite). Everythign is really well made, and you don't go home hungry!
Know before you go: Craft cocktails are different and you have to go with an open mind, also, you will line up at the door, place your order, be handed a number and then go sit (Panera style)- this can be a bit awkward as you can have a number and possibly not a table?!
