Lunch in Peterborough
There's a running discussion on PTBO and region's best eats here:
St. Veronus is a good choice, though their best items are mussels and beer. If those aren't at the top of your list of delicious eats then look elsewhere. (Though those items are very delicious there!)
If it's a nice day, then I would recommend the patio at Kettle Drums. Their pizzas are amazing. The patio is nice. Elements also has a nice patio and the indoor space is great as well. They serve mostly tapas, which are pretty tasty (having only gone once.)
If it is Thai curry you are after then Cosmic Charlies. Indian Curry? Then Curry Village. For casual pub then Old Stone. All of these have above average though not mind blowing food.
