I'm not sure I understand why there are so many negative reviews of this place. Terroni does such a great job on their food - and I would never want to change it or dilute it! The waiter we had also was super friendly.
La Bettola seems to be a more compact version of Terroni in terms of its menus, maybe for the business crowd? The food came out in record time, and was delicious.
I ordered the papparadelle with lamb, which was super good! I love their wine list too - some really obscure wines from Italy that you would never find anywhere else.
The salted caramel budino was fantastic - a little bit of crunch, and very creamy. I will return!
