Due to the COVID-19 pandemic, many government authorities have placed restrictions on social gatherings. As a result, you may see reduced or no availability in certain locales. Bookings may be subject to cancellation by the restaurant or OpenTable to comply with such restrictions. During this time, there are still ways to support restaurants.
Osteria Ottimo is a hidden gem in the suburbs. Very good authentic Italian food in a nice atmosphere that rivals some of the higher end restaurants you would find in downtown Chicago. One of my family's favorite places.
