Maoz falafel joints are apparently not uncommon around the world - there's a chain of them that covers the US and Europe, taking in the Netherlands and France along the way. There's even a branch in London, where I live, but I've never stopped in for a falafel fix - a situation that a night on the tiles in Barcelona prompted me to fix last week.
Happily, Maoz is just what you need after a night on the beers - falafel served in a big pillowy pitta with enough salads to satisfy the hungriest herbivore and enough hot sauces to damp down the sort of bravado that Spanish beer can inspire. (Maoz is not entirely vegan, but the vast majoity of what it serves is animal free, and those things that aren't are obviously so - coleslaw in mayonnaise, for example.)
Maoz gives you two falafel-y options: three falafels in a pot which you fill up with salads, or four in a pitta that you pull off the same stuff-as-much-in-as-you-can trick with. I opted for the pitta, and got heartily stuck in to the Jenga-like game of seeing just how many different types of salads, veggies, and sauces I could forcibly wedge into the bread. Deep fried cauliflower (deliciously greasy) made the cut, as did olives, cornichons, a fairly bland carrot salad and a more interesting caraway-flavoured cabbage arrangement, some hot sauce and a pickled chilli for good measure.
And that's about half the range of extras that Maoz stumps up, alas, my pitta was already bursting at the seams and was promptly whisked outside to be swallowed down in record speed.
There are many falafel places in the world, and Maoz isn't particularly unique or outstanding among them, but as a tasty means of sopping up beer, it definitely gets my vote.
