Best Chicken and Let's Eat portray a nice mix of romance, love for food and comedy...

In both the doctors have a complicated childhood. Their childhood influence in their medical careers and personal life.

Both dramas are mainly about revenge, both have the same male lead - Yoo Seung Ho as student (but in Remember he'll become a lawyer) and in both dramas he has tragic past.

Both of these dramas feel very similar: college/university life, social problems, bullying, misunderstandings and betrayals.

Both dramas have similar feels in the hospital setting and both don't have romance. But Life is more about political matters and don't have so much surgeries as Heart Surgeons.

Let's Eat and Drinking Solo are about love for food, both have mukbang and nice characters you can relate to.
