I'm writing this as I am still eating because it's too good to put off! With so many poke places coming out along Eastern and in the Spring Valley area... and with the several I've tried.. Poke Poku is one of the better options!
First, their $5 lunch deal for a sushi burrito is TOOOOO GOOOD to last. You can add as many mix ins as you want.. which in turn will leave you with a 1 lb burrito that might as well be a bowl. You get 3 pieces of fried gyoza and all the tea water stuff you can drink!
Plus if you check in on YELP you get 10% off!
I got 2 burritos (one filled to the core) for $9.74 (and tipped them a couple of bucks because it's so worth it). It's also worth the 30-45 minute wait (which I attribute to only 2 people working the line and cash register.. but I'm sure it'll change once kinks are worked out). Their staff are very nice -- he forgot to charge me for a drink and gave it complimentary (which I'll repay in more tips later on).
My recommendation is for the Las Vegas style which has their Gucci Sauce (secret recipe they say), spicy mayo, and ponzu. For a spicy chicken like me, it gives you a nice warmth without pain on your tongue.
