I have been to Shishawarma a few times over the past 2 years, it is a few blocks from the Eaton Centre, but at a walkable distance. Not the most spectacular place, and I'm unsure of the hygiene and sanitary practices here.
I usually get the chicken shawarma, which is good and filling. Shisha is decent as well, they have a good amount of flavours to choose from. There is always someone coming around to check to make sure the hookah pipes are working and will give extra coals if asked.
It's a good place to relax alone and with a group as well, noise level never bothered me. It seems to start getting busier around 10pm, but before that there is no problem getting a seat outside or inside.
I will go back to Shishawarma just for the relax time.
