Can't go wrong. I often go here for delicious wraps. The barg and tikka wraps are my go-to's and have biggg chunks of beef. There's really not much else to say. There has been the odd time I've been there and the wrap didn't have enough vegetables and was consequently limp, but I am generally satisfied with their reliability.
FYI prices recently went up. There's also been a guy working in the kitchen that seriously looks like Rambo from First Blood - so jacked! Entertainment value +1.
