I've heard lots of good reports of Moaz over the years, but I've always been too tempted by other places in the area that I know to be good (such as Beetroot) to try it out. I'm glad I waited.
I'll start with what's good: the price. For its location, their pricing is pretty reasonable (£5.90 for a "Meal Deal").
That's about where it ends.
When we arrived we stood in front of the counter for a good few minutes before either of the people behind it acknowledged our presence. We then sat an an unclean table for around 10 minutes waiting for our "fast food" to appear.
I had a meal deal. The chips were the 2nd worst I've ever had (the worst were at a festival and undercooked). I had a few and left the rest (this doesn't normally happen with me). The falafel itself was OK (cauldron standard, possibly slightly nicer), but I didn't like the pitta itself (not fresh enough), humous or the "free salad bar" toppings.
I wouldn't go back.
(in case you're wondering what I do constitute as good falafal, I highly rate the stuff that Goodness Gracious sell at festivals).
After reading through your blog you seem like someone who is insanely hard to please! I love Maoz! I had it loads of times in Amsterdam and it was great. Maybe it's better over there... Doubtful...
