Tandem is amazing. We went to the original location for lunch without a reservation, and they told…read moreus that they were booked up, but that they had a second location a few blocks away that could likely accommodate us. They picked up the phone, made a call, and a table was secured. We walked over, and were immediately seated. The waiter brought a box of multiple shapes of pasta, explained what each was called, and which sauces were appropriate with each. We ended up ordering caprese salad (the freshest buffalo mozzarella we ever had), one pasta, and the bread loaf filled with meatballs and ragu. We were in heaven, and the portions were tremendous. We left stuffed, satisfied, and paid about 45 euros for the meal. Highly recommended!
