During my 6 month stay in San Diego, I went to the Cheesecake Factory 3 times. Twice were JUST for the cheesecake and once I, unfortunately, included dinner. My meal was honestly disappointing. The meal itself was overpriced and the food was bland and uninspired. Also, I went on a Tuesday night around 8 and had to wait an hour with my husband for a very cold table beside the door. In my experience, that shouldn't be a busy time.
The cheesecake is to-die-for. And it's well worth picking one up on your way home from a much better, less over-rated restaurant.
Cheesecake is a 5, food is a 1.
