Based on many recommendations, checked out The Corner Grille, 806 Pleasant Street, Worcester, MA. Possibly the thinnest crust I've ever had. I'm a purest - cheese, pepperoni, sausage is about it . . . but I was talked into their Chicken Caesar Salad Pie with caesar dressing, chicken, tomatoes, parmesan and mozzarella all topped with a cold chopped lettuce tossed in the dressing. It was delicious! It easily fed two of us for $11.99. I liked it so much that I'm considering going back to try other pizzas such as The Buffalo Pie, Harvest Moon Pie (butternut squash and pumpkin seeds are a few of the toppings), Baked Potato Pie or the South-Westside barbecue Pie. For the not so brave (the old me!) there are traditional toppings as well. The place is small and parking can be limited at peak times but it's worth a visit.
