This restaurant is where the Bellwoods Restaurant (Tom) used to be. The place is clean and the food is good and reasonably priced. I've eaten at It's All GRK and done takeout several times and it's been good every time. The prices are slightly above average if you're used to Swarma or Gyros on the Danforth but it's all good and worth it IMO.
The Souvlaki on a Pita is excellent, the Tzatzki is nice and garlicy. It's a bit different - they add GRK fries to the actual Pita. Same for the Gyros and although I'm not a huge fan of Gyros normally, these are pretty darn good!
I would recommend this place for fast Greek food with lots of flavour.
