Carveli provides the ultimate in comfort food. Their pizzas are of the heftier variety, with thick crust and abundant cheese. My personal favourite is the Greek-style bean soup, or Fasolada. It's always accompanied by their made-in-house lightly fried pita bread triangles, perfect for dipping.
I'm also a big fan of their pita-based sandwiches, the chicken brochette in particular. Served with a massive helping of tzatziki sauce, it's a messy treat. The meat is not as tender as that served at Marathon Souvlaki, but the fresh pita is far superior.
The two main issues I have with Carveli are that delivery times can be exceedingly long, resulting in less-than-hot food upon arrival, and that the restaurant itself is a bit of a dive. Do not go there looking for ambience, and you won't be disappointed.
