I have to kind of agree with Lambert P.'s review in comparing it to Villa Madina - fast food Middle Eastern; HOWEVER, Villa Madina gives you more bang for your buck.
I've only been once, on a Sunday afternoon and it was very quiet in there.
I'll get straight and to the point.
Pros: friendly service, nicely flavoured meat.
Cons: skimpy on the condiments (e.g. imagine being on a diet and you're only allowed 1 TBSP of hummus, well it was spread on that thin); only three little onion pieces and about four little turnip pieces; green pickles had a rancid taste but that could have been a spice they used - I discarded them. Again, it was probably a spice because I wasn't ill after eating it.
Shawarmas really fill me up and I usually can't eat the whole thing but I was actually still hungry after this one. Tip: if you're a guy, buy two because one will NOT fill you up.
I might return but that would have to depend on how desperate my shawarma craving is that day.
