Putting aesthetic considerations to one side, I'm not sure I'm convinced by the argument that Dominoes will put other local pizza takeaways out of business. That said, I don't know the takeaways you're talking about so you may well be right.
However, Forest Hill has the Pizza Hut takeaway and Al Forno - big multi national and small independent respectively. They cater for totally different markets - I've lived in Forest Hill since 2002 and have never once ordered a pizza from Pizza Hut - I don't like their pizzas. But Al Forno is an entirley different creature, wood fired thin crust pizzas and absolutley delicious and the chap who delivers to our street is just lovely.
