It's not particularly meaningful to say this is the best falafel in Seattle because, frankly, this is the ONLY real contender in my mind. Having spent my college years surrounded by a lot of amazing falafel, I was disappointed in the lack of good (or even bad) falafel in Seattle. Until I tried Zaina. I will say it is some of the best falafel I've had, period.
I'm not sure about the rest of their menu because everytime I go there I get the exact same thing - the falafel sandwich. The falafel is done to perfection, the sauces are yummy, and if you can handle spice, the spicy sauce just MAKES IT. I think it's 4.99? A price you can't beat.
This week was the first time I went in the evening and sampled out the bar/lounge. The lounge is big and expansive, with a HUGE projector screen. Playing on the screen are Middle Eastern music videos. I totally go in for this sort of thing, I love the foreign music videos, so this made me happy. The music isn't too loud, so you can definitely enjoy your conversation, but it's there if you want to check it out. We ordered the grape hookah, for 15 dollars, and a few drinks. The hookah was great, the drinks, less so. I'd just say don't order anything with tonic because they are using bottled tonic and it was flat. Stick to the hard liquor w/non carbonated mixers or beer and I'm sure it's fine.
Conveniently located near Belltown, it's a great place to hit up for some food once you've gotten sauced at one of the Belltown bar's after-work happy hours and need to get some nourishment in you.
